How to Buy Diamonds, Pearls, Colored The point unit—equal to one one-hundredth of a carat 0. While even a pale pink or blue hue may increase the fußball-live.net of a diamond, more intense coloration is usually considered more desirable and commands the highest prices.
In , the two companies merged to form De Beers Consolidated Mines , which once had a monopoly over the world's diamond market. The diamond cutters of Antwerp are world renowned for their skill.
More than 12, expert cutters and polishers are at work in the Diamond District , at workshops, serving 1, firms and 3, brokers and merchants.
In the 21st century, the technology to produce perfect diamonds synthetically was developed. Diamonds produced by the latest technologies are visually identical to mined, naturally occurring diamonds.
It is too early to assess the effect of future wide availability of gem-quality synthetic diamonds on the diamond market, although the traditional diamond industry has taken steps to try to create a distinction between diamonds dug from the ground and diamonds made in a factory, in part by downplaying the fact that diamonds from both sources are actually visually identical.
The most familiar usage of diamonds today is as gemstones used for adornment —a usage which dates back into antiquity. The dispersion of white light into spectral colors is the primary gemological characteristic of gem diamonds.
In the twentieth century, gemologists have developed methods of grading diamonds and other gemstones based on the characteristics most important to their value as a gem.
Four characteristics known informally as the "four Cs" are now commonly used as the basic descriptors of diamonds: This system was developed by Gemological Institute of America in as internationally recognized standard to evaluate diamonds characteristics.
Most gem diamonds are traded on the wholesale market based on single values for each of the four Cs; for example knowing that a diamond is rated as 1.
More detailed information from within each characteristic is used to determine actual market value for individual stones.
Consumers who purchase individual diamonds are often advised to use the four Cs to pick the diamond that is "right" for them. Other characteristics also influence the value and appearance of a gem diamond.
These include physical characteristics such as the presence of fluorescence as well as the diamond's source and which gemological institute evaluated the diamond.
Cleanliness also dramatically affects a diamond's beauty. There are two major non-profit gemological associations which grade and provide reports, informally referred to by the term certificate or cert , which is a misnomer for many grading reports on diamonds; while carat weight and cut angles are mathematically defined, the clarity and color are judged by the trained human eye and are therefore open to slight variance in interpretation.
These associations are listed below. Within the last two decades, a number of for-profit gemological grading laboratories have also been established, many of them also based in Antwerp or New York.
These entities serve to provide similar services as the non-profit associations above, but in a less expensive and more timely fashion. They produce certificates that are similar to those of the GIA.
The carat weight measures the mass of a diamond. One carat is defined as milligrams about 0. The point unit—equal to one one-hundredth of a carat 0.
All else being equal, the price per carat increases with carat weight, since larger diamonds are both rarer and more desirable for use as gemstones.
The price per carat does not increase linearly with increasing size. Instead, there are sharp jumps around milestone carat weights, as demand is much higher for diamonds weighing just more than a milestone than for those weighing just less.
As an example, a 0. Jewelers often trade diamonds at negotiated discounts off the Rapaport price e. In the wholesale trade of gem diamonds, carat is often used in denominating lots of diamonds for sale.
Because of this, diamond prices particularly among wholesalers and other industry professionals are often quoted per carat, rather than per stone.
Total carat weight t. Diamond solitaire earrings, for example, are usually quoted in t. Clarity is a measure of internal defects of a diamond called inclusions.
Inclusions may be crystals of a foreign material or another diamond crystal, or structural imperfections such as tiny cracks that can appear whitish or cloudy.
The number, size, color, relative location, orientation, and visibility of inclusions can all affect the relative clarity of a diamond.
Diamonds become increasingly rare when considering higher clarity gradings. Those that do not have a visible inclusion are known as "eye-clean" and are preferred by most buyers, although visible inclusions can sometimes be hidden under the setting in a piece of jewelry.
Most inclusions present in gem-quality diamonds do not affect the diamonds' performance or structural integrity. When set in jewelry, it may also be possible to hide certain inclusion behind mounting hardware such as prongs in a way that renders the defect invisible.
However, large clouds can affect a diamond's ability to transmit and scatter light. Large cracks close to or breaking the surface may increase the likelihood of a fracture.
The finest quality as per color grading is totally colorless, which is graded as D color diamond across the globe, meaning it is absolutely free from any color.
However, when studded in jewellery these very light colored diamonds do not show any color or it is not possible to make out color shades. These are graded as E color or F color diamonds.
Diamonds which show very little traces of color are graded as G or H color diamonds. Slightly colored diamonds are graded as I or J or K color.
A diamond can be found in any color in addition to colorless. Some of the colored diamonds, such as pink, are very rare.
A chemically pure and structurally perfect diamond is perfectly transparent with no hue , or color. However, in reality most gem-sized natural diamonds are imperfect.
Depending on the hue and intensity of a diamond's coloration, a diamond's color can either detract from or enhance its value.
For example, most white diamonds are discounted in price as a more yellow hue is detectable, while intense pink or blue diamonds such as the Hope Diamond can be dramatically more valuable.
The Aurora Diamond Collection displays a spectacular array of naturally colored diamonds, which occur in every color of the rainbow. Most diamonds used as gemstones are basically transparent with little tint, or white diamonds.
The most common impurity, nitrogen , replaces a small proportion of carbon atoms in a diamond's structure and causes a yellowish to brownish tint.
The GIA has developed a rating system for color in white diamonds, from D to Z with D being "colorless" and Z having a bright yellow coloration , which has been widely adopted in the industry and is universally recognized, superseding several older systems.
The GIA system uses a benchmark set of natural diamonds of known color grade, along with standardized and carefully controlled lighting conditions.
Diamonds with higher color grades are rarer, in higher demand, and therefore more expensive, than lower color grades. Oddly enough, diamonds graded Z are also rare, and the bright yellow color is also highly valued.
N—Y usually appear light yellow or brown. In contrast to yellow or brown hues, diamonds of other colors are more rare and valuable. While even a pale pink or blue hue may increase the value of a diamond, more intense coloration is usually considered more desirable and commands the highest prices.
A variety of impurities and structural imperfections cause different colors in diamonds, including yellow, pink, blue, red, green, brown, and other hues.
Diamonds with unusual or intense coloration are sometimes labeled "fancy" in the diamond industry. Intense yellow coloration is considered one of the fancy colors, and is separate from the color grades of white diamonds.
Gemologists have developed rating systems for fancy colored diamonds, but they are not in common use because of the relative rarity of such diamonds.
Diamond cutting is the art and science of creating a gem-quality diamond out of mined rough. The cut of a diamond describes the manner in which a diamond has been shaped and polished from its beginning form as a rough stone to its final gem proportions.
The cut of a diamond describes the quality of workmanship and the angles to which a diamond is cut. Often diamond cut is confused with "shape".
There are mathematical guidelines for the angles and length ratios at which the diamond is supposed to be cut in order to reflect the maximum amount of light.
Round brilliant diamonds, the most common, are guided by these specific guidelines, though fancy cut stones are not able to be as accurately guided by mathematical specifics.
The techniques for cutting diamonds have been developed over hundreds of years, with perhaps the greatest achievements made in by mathematician and gem enthusiast Marcel Tolkowsky.
He developed the round brilliant cut by calculating the ideal shape to return and scatter light when a diamond is viewed from above.
The modern round brilliant has 57 facets polished faces , counting 33 on the crown the top half , and 24 on the pavilion the lower half. The girdle is the thin middle part.
The function of the crown is to refract light into various colors and the pavilion's function to reflect light back through the top of the diamond.
The culet is the tiny point or facet at the bottom of the diamond. This should be a negligible diameter, otherwise light leaks out of the bottom.
Tolkowsky's calculations included neither a culet nor a girdle. However, a girdle is required in reality in order to prevent the diamond from easily chipping in the setting.
The thick part of the girdle is normally about 1. The further the diamond's characteristics are from the Tolkowsky's ideal, the less light will be reflected.
However, there is a small range in which the diamond can be considered "ideal". Tolkowsky's calculations can be repeated for a narrow range of pavilion angles.
Such calculations show a slightly larger table percentage, and a trade-off between pavilion angle and crown angle. Today, because of the relative importance of carat weight among buyers, many diamonds are often intentionally cut poorly to increase carat weight.
There is a financial premium for a diamond that weighs the desirable 1. Neither of these changes makes the diamond appear any larger, and both greatly reduce the sparkle of the diamond.
A poorly cut 1. The depth percentage is the overall quickest indication of the quality of the cut of a round brilliant.
Another quick indication is the overall diameter. Typically a round brilliant 1. Mathematically, the diameter in millimeters of a round brilliant should approximately equal to 6.
Diamonds do not show all of their beauty as rough stones; instead, they must be cut and polished to exhibit the characteristic fire and brilliance that diamond gemstones are known for.
Diamonds are cut into a variety of shapes that are generally designed to accentuate these features. Diamonds which are not cut into a round brilliant shape are known as "fancy cuts.
Newer cuts that have been introduced into the jewelry industry are the "cushion" "radiant" similar to princess cuts, but with rounded edges instead of square edges and Asscher cuts.
Many fancy colored diamonds are now being cut according to these new styles. Generally speaking, these "fancy cuts" are not held to the same strict standards as Tolkowsky-derived round brilliants and there are less specific mathematical guidelines of angles which determine a well-cut stone.
Cuts are influenced heavily by fashion: The princess cut is also popular amongst diamond cutters: The past decades have seen the development of new diamond cuts, often based on a modification of an existing cut.
Some of these include extra facets. These newly developed cuts are viewed by many as more of an attempt at brand differentiation by diamond sellers, than actual improvements to the state of the art.
The quality of a diamond's cut is widely considered the most important of the four Cs in determining the beauty of a diamond; indeed, it is commonly acknowledged that a well-cut diamond can appear to be of greater carat weight, and have clarity and color appear to be of better grade than they actually are.
The skill with which a diamond is cut determines its ability to reflect and refract light. In addition to carrying the most importance to a diamond's quality as a gemstone, the cut is also the most difficult to quantitatively judge.
A number of factors, including proportion, polish, symmetry , and the relative angles of various facets, are determined by the quality of the cut and can affect the performance of a diamond.
A diamond with facets cut only a few degrees out of alignment can result in a poorly performing stone. For a round brilliant cut, there is a balance between "brilliance" and "fire".
When a diamond is cut for too much "fire", it looks like a cubic zirconia , which gives off much more "fire" than real diamond. A well-executed round brilliant cut should reflect light upwards and make the diamond appear white when viewed from the top.
An inferior cut will produce a stone that appears dark at the center and in extreme cases the setting may be seen through the top of the diamond as shadows.
Several different theories on the "ideal" proportions of a diamond have been and continue to be advocated by various owners of patents on machines to view how well a diamond is cut.
These advocate a shift away from grading cut by the use of various angles and proportions toward measuring the performance of a cut stone.
A number of specially modified viewers and machines have been developed toward this end. Hearts and Arrows viewers test for the " hearts and arrows " characteristic pattern observable in stones exhibiting high symmetry and particular cut angles.
Closely related to Hearts and Arrows viewers is the ASET which tests for light leakage, light return, and proportions.
Detractors, however, see these machines as marketing tools rather than scientific ones. The GIA has developed a set of criteria for grading the cut of round brilliant stones that is now the standard in the diamond industry and is called Facetware.
The process of shaping a rough diamond into a polished gemstone is both an art and a science. The choice of cut is often decided by the original shape of the rough stone, location of the inclusions and flaws to be eliminated, the preservation of the weight, popularity of certain shapes amongst consumers and many other considerations.
Oddly shaped crystals such as macles are more likely to be cut in a fancy cut —that is, a cut other than the round brilliant—which the particular crystal shape lends itself to.
Since the per carat price of diamond shifts around key milestones such as 1. Du kan lösa in poäng mot nya resor eller som betalning för hyrbilar i framtiden.

Dirt or grease on the top of a diamond reduces its luster. Water, dirt, or grease on the bottom of a diamond interferes with the diamond's brilliance and fire.
Even a thin film absorbs some light that could have been reflected to the viewer. Colored dye or smudges can affect the perceived color of a diamond.
Historically, some jewelers' stones were misgraded because of smudges on the girdle, or dye on the culet.
Current practice is to clean a diamond thoroughly before grading its color. Maintaining a clean diamond can sometimes be difficult as jewelry settings can obstruct cleaning, and oils, grease, and other hydrophobic materials adhere well to a diamond.
Many jewelers use steam cleaners. Some jewelers provide their customers with ammonia -based cleaning kits; ultrasonic cleaners are also popular.
Historically, it has been claimed that diamonds possess several supernatural powers:. Because of their extraordinary physical properties , diamonds have been used symbolically since near the time of their first discovery.
Perhaps the earliest symbolic use of diamonds was as the eyes of Hindu devotional statues. Vajra is the word for diamond and ayudham means weapon in Sanskrit.
Another name for it was Agira which means fire or the sun. In fact there are 14 names counted to be given to a diamond in traditional Hinduism.
The oldest dated printed book in the world is called the Diamond Sutra , a Chinese text dating from and was found in the Mogao Caves.
Sutras are most used to describe the teachings of Buddha. In this case the title of the Sutra refers not to the diamond itself but to a 'diamond blade that will cut through worldly illusion to illuminate what is real and everlasting'.
Jewel imagery forms a central part of Buddhism: The book presently resides in the British Library. Many cultures use divine intervention to explain the origin and creation of gemstones, and diamonds were no exception to this.
In Greek mythology for example it was the youth on the island of Crete that disturbed Zeus and who were then as a form of punishment transformed into the adamas.
Philosophers however had a more naturalistic approach to explain the origin of gems: Plato for example believed gemstones were a consequence of fermentation in the stars, where a diamond actually formed the kernel of gold-bearing mass.
In later times, Robert Boyle actually believed that gems including a diamond were formed of clear, transparent water, and that their colors and characteristics were derived from their metallic spirit.
The diamond is the birthstone for people born in the month of April, and is also used as the symbol of a sixty-year anniversary , such as a Diamond Jubilee see hierarchy of precious substances.
In a system of heraldry by gemstone occasionally used in the past for the arms of nobles, diamond was used to represent the color sable, or black.
The origin of the custom to use diamonds in rings, and more recently, in engagement rings , can be traced back to the Middle Ages and even the Romans.
The Romans valued the diamond entirely on account of the supernatural powers they ascribed to it. Pliny wrote that a diamond baffles poison, keeps off insanity, and dispels vain fears.
On this account it was recommended as the stone to be set in wedding or espousal rings—not on account of its beauty therefore, which was described by Isidore of Seville as a small stone devoid of beauty.
In more recent times a Parisian Oracle of mystic subjects, the Baron d'Orchamps, announced the diamond, if worn on the left hand warded off evil influences and attracted good fortune and since he had fashionable clients the word spread and the wearing of the diamond on the left hand became in itself a fashion.
One of the first occurrences of the diamond engagement or wedding ring can be traced back to the marriage of Maximilian I then Archduke of Austria to Mary of Burgundy in The popularity of the diamond ring as an engagement ring for a much wider audience can be traced directly to the marketing campaigns of De Beers , starting in In the early 20th century, a chairman of De Beers optimistically predicted that the diamond trade would prosper "so long as men are foolish and women are vain.
Today, the brilliant is still the most popular diamond shape for an engagement ring. About 70 percent of the sold diamonds are brilliants.
The increase in online sales are disrupting the market for diamonds by bringing greater transparency to an industry that has traditionally relied on opacity.
In some of the more politically unstable central African and west African countries, revolutionary groups have taken control of diamond mines , using proceeds from diamond sales to finance their operations.
Diamonds sold through this process are known as conflict diamonds or blood diamonds. Major diamond trading corporations continue to fund and fuel these conflicts by doing business with armed groups.
In response to public concerns that their diamond purchases were contributing to war and human rights abuses in central Africa and West Africa , the United Nations , the diamond industry and diamond-trading nations introduced the Kimberley Process in , which is aimed at ensuring that conflict diamonds do not become intermixed with the diamonds not controlled by such rebel groups, by providing documentation and certification of diamond exports from producing countries to ensure that the proceeds of sale are not being used to fund criminal or revolutionary activities.
This is a very stringent tracking system of diamonds and helps protect the 'conflict free' label of Canadian diamonds. From Wikipedia, the free encyclopedia.
Diamond mining in India. Big Hole and De Beers. Richards also discuss Pliny's referral in Book XXXVI, 54 of the stone of "Naxos" as being adamas , and which had long been used for cutting and polishing.
A chief product of Naxos has long been a high grade of amorphous corundum which was used as an abrasive. Richards, Ohio State University, , page They further discuss his referral to the adamas coming from the "east" through Armenian traders but they show this was actually based on an erroneous interpretation of Theophrastus.
Williams, Diamond Mines of South Africa, New York, BF Buck Company, argues that the stone named " adamas " by the Greek and further referred to by Pliny was most likely a sapphire since this was a much more abundant stone, even amongst traders in Asia, than diamond especially when used in the context of " adamas " being an ornamental stone and not used in an "industrial" context of engraving gems.
There seems to be a consensus over a large period of time that in fact the " adamas " was not a diamond, but mostly any type of corundum, several other minerals such as spinel were probably confused with diamonds as well; particularly because of a similarity in hardness and their availability in the Mediterranean area.
He describes diamonds being worn as long as years ago, recorded in ancient Hindu writings. George Frederick Kunz in 'A Curious Lore of Precious Stones' describes how a diamond in ancient times is worn on the forehead until the early 19th century this was a tradition believed to bring good luck.
