An alternative example of such a price fall caused by introduction of a new simulant strongly undermining prices was the permanent fall in natural pearl prices with the introduction of cultured pearls[citation needed] . The mechanism by which prices were affected was complex. In part because of the social acceptability of wearing cultured pearls to much of the market, customers migrated from the natural to the lower-price cultured product[citation needed] . This altered the supply and demand situation for natural pearls and perhaps the overall prestige of pearls in general was lowered[citation needed] . In 

cases where synthetic stones have been much less socially acceptable to the market as a replacement for the natural version, the prestige of the natural stones has been retained[citation needed] . Thus increased availability and lowered prices of synthetics may or may not have major implications for the future price of natural diamonds[citation needed] . In addition, the introduction of synthetic rubies in the late 19th century did not appear to have a permanent effect on the price of natural rubies[citation needed] .

It is much cheaper to produce diamonds through artificial synthesis than to mine them[citation needed], although currently the cost of synthesis is still significant. The inability to guarantee that a diamond is naturally occurring could undermine the premium price still currently charged over synthetic diamonds [8] However, new technological advances have allowed some independent gem labs such as GIA (Gemological Institute of America) to issue a specific Synthetic Diamond Grading Report which identifies a diamond as laboratory-grown and laser inscribes it with “laboratory grown”

Although it was originally impossible to produce diamonds artificially, techniques to do so have been around since the 1950s and have become routine in recent years. Modern techniques can produce diamonds of essentially any desired chemistry or size[citation needed] and can even be made more perfect than naturally occurring ones, synthetic diamonds are genuinely diamonds albeit not naturally occurring. Although some manufacturers do label their synthetic diamonds with serial numbers there is no guarantee that a given diamond is not man made, although sometimes an unnatural chemical composition or pattern of flaws may suggest a diamond is synthetic

Rough diamond prices have historically been impacted by the mining companies controlling supply, most notably De Beers. However, post the dismantling of the De Beers cartel in 2001, the industry is now more fragmented resulting in a higher percentage of diamond sales taking place in the form of auctions and other forms of open-market sales.

Polished diamond prices vary widely depending on a diamond's carat, color, clarity and cut, sometimes referred to as the 4 C's. In contrast to precious metals, there is no universal world price per gram for diamonds. The industry refers to price guides such as the Rapaport Diamond Report, the Troy Diamond Report, PriceScope,[4] Ajediam Antwerp Diamonds Monthly[5] and The Gem Guide, which are published weekly, monthly or quarterly. Gemstone specialty organizations have varying standards which can be used to aid in diamond identification and pricing, including GIA, HRD[6] and IGI. These organizations focus on research and education, which they pass on to their members and the public.

The value of diamonds as an investment is of significant interest to the general public, because they are expensive gemstones, often purchased in engagement rings, due in part to a successful 20th century marketing campaign by De Beers.[1][2][3] The difficulty of properly assessing the value of an individual gem-quality diamond complicates the situation. The end of the De Beers monopoly and new diamond discoveries in the second half of the 20th century have reduced the resale value of diamonds.

No one has ever explained why such a bulky step cut was applied to this diamond. It seems that priority was given to weight retention, since the prestige of a diamond depended at that time primarily on its weight. Dr. Kunz state "that this unprecedented number of facets was given the stone not to make it more brilliant, but less brilliant. The stone was of yellow colour, and it was thought better to give it the effect of 

a smothered, smoldering fire than one of flashing radiance."** The stone has an unusual feature, in a yellow diamond, of retaining its color by artificial light.*** The designers decided to ignore the modern rules of proportioning (such as those introduced to America by Morse) since these would have produced a Brilliant of well below the magic figure of 100 carats, which entitles a diamond to the name of 'Paragon'. Here, even the classic proportions would not have done -- a Brilliant with the width and length of this stone (27 mm × 28.25 mm) with 45° angles would have barely weighed 100 carats.

The Tiffany Yellow, set in Jean Schlumberger's "Bird on the Rock" brooch.

Since being viewed by this distinguished visitor, the Tiffany Yellow has been seen by millions of others in almost seventy years of continuous display in Tiffany's store. It has also been shown at numerous exhibitions: they include the Chicago Columbian in 1893, the Pan-American in 1901, the Chicago Century of Progress in 1933-34 and the New York World's Fair in 1939. The first occasion on which the diamond was worn was in 1957 at the Tiffany Ball held in Newport, Rhode Island, when the chairwoman of the ball, Mrs. Sheldon Whitehouse, had the honor of wearing it, 

mounted for the occasion in a necklace of white diamonds. In 1971 the Tiffany Yellow returned to South Africa for the exhibition which marked the centennial celebrations of the Kimberly Mine. After an absence of forty years from London, Tiffany's re-opened their branch in Old Bond Street in 1986, and displayed the diamond to herald its return.

The Diamond’s origin is well known to gemologists, historians and jewelry collectors. Discovered in the Kimberley diamond mines in South Africa in 1877, the 287.42-carat rough stone was acquired the following year by founder Charles Lewis Tiffany. It solidified Mr. Tiffany’s reputation as the “King of Diamonds” and made his enterprise the world’s diamond authority.

The Klopman diamond is a fabulous, legendaryand huge diamond, said to have a curse associated with it.

The Klopman diamond was originally the subject of a traditional joke, a typical version of which is:

A businessman boarded a plane to find, sitting next to him, an elegant woman wearing the largest, most stunning diamond ring he had ever seen. He asked her about it.

“This is the Klopman diamond,” she said. “It is beautiful, but it’s like the Hope diamond; there is a terrible curse that goes with it.” “What’s the curse?” the man asked. She said “Mr. Klopman.”

Due to the use of the name “Klopman” and the somewhat dark humor, and the fact that it was one of Myron Cohen’s standards, this joke is sometimes characterised as Yiddish in origin. Some commentators maintain that names other than Klopman would not be as funny, and point to the fact that this joke has survived essentially unaltered for decades.

A later joke of Myron Cohen, similar in nature, goes as follows:

Further evidence that the Tiffany Yellow Diamond must have originated in the claims of the historically important French Company is show by the fact that the gen was shipped to Paris. Experts there studied it for one year before it was cut under the supervision of the distinguished gemologist George F. Kunz in 1878. It yielded a cushion-cut brilliant of 128.54 (metric) carats, measuring 27 mm wide, 28.25 mm long and 22.2 mm deep. It was given a total of 90 facets: 48 on the pavilion, 40 on the crown, plus the table and culet. The extra facets were cut not to give the diamond more sparkle, rather to make it smolder as if it were lit by fire. The gem is high in fluorescence and retains this rich color in artificial light, but is even more beautiful by day.
