The year became 1867. A farmer who was snoozing below a tree, noticed an exceedingly puny golf ball-sized rock.
The finder can be forgiven for not knowing that the 21.25-carat brilliant light-golden lump becomes a diamond. After all, diamonds have been colorless, right? So while his spouse gave the brownish-yellow stone away to a curious neighbor who sent it to Johannesburg for testing, best then turned into it diagnosed as a diamond. After being cut to a ten.73-carat cushion form, it changed into named the Eureka (an interjection meaning “I observed it!” frequently exclaimed after a vital discovery) and placed on show at the Paris Exhibition of 1868. Now, nearly a hundred and fifty years after its development, the Eureka nonetheless stays prophetic, although not a prodigious, first. Here’s why. clik here
A polished diamond weighing almost eleven carats was boulder-sized by using 19th century standards. Gemologist Max Bauer, writing round 1900, wrote that 1 and a pair of carat stones had been rarities in jewelry shops until the South African diamond rush of 1868. By 1872, all that modified considerably while South Africa’s mines had jumped annual international diamond production tenfold and average sizes had catapulted thus. Carat-plus sizes had been not a dream but a truth—albeit a high priced one. Indeed, simply 38 years later, the largest-ever diamond, the Cullinan, weighing 3,106.75 carats, turned into found close to Pretoria.
Fortunately, size became the handiest half of Eureka’s story. The diamond changed into as uncommon in the shade as it became in size. Yellow as a dandelion, the gem certified as a seldom-discovered breed of a diamond, then—and now—referred to as a “fancy shade.” Sensing that South Africa could sooner or later turn out to be as associated with fancy yellow diamonds as Burma was with best-coloration rubies, George F. Kunz, the leader gem buyer at Tiffany’s and perhaps the finest gemological skills scout in history, paid the then-lordly sum of $18,000 for a tremendous 287.02-carat South African hard in 1877. Bought as a lot for its hue as its heft, the rock might show a much greater sensation than the Eureka.
After a yr of making plans, the difficult becomes cut in Paris to a 128.51-carat cushion.
This becomes a farseeing selection. Against the advice of his contemporaries, Kunz chose the precise identical cutting fashion for his large gem as the owners of the Eureka had: a cushion shape. His intention changed to emphasize the depth of color as plenty as the immensity of size. Named the Tiffany Diamond, this giant cushion cut became to turn out to be the most well-known diamond on show in America, given feature billing at each the 1934 and 1939 World’s Fairs. Indeed, until jeweler Harry Winston donated the deep-blue Hope Diamond to the Smithsonian Institution in 1958, the Tiffany Diamond turned into America’s flagship fancy-color diamond.
This history is vital as it foreshadows the new growth in fancy yellow diamonds.
What did Kunz see in these stones that it took the relaxation of diamond exchange more than a century to discover? And how did his selections concerning cutting yellow diamonds assume the present day?
Fancy Yellow Diamonds：From Cape To Canary
In 1940, the remaining yr of his life, F. Scott Fitzgerald wrote, “There are no 2d acts in American lives.” While that may be so for people, it’s far decidedly now not so for diamonds–yellow diamonds special. Here’s why and the way.
Did you already know that 98% of the sector’s diamonds incorporate nitrogen–which acts, to various tiers, as a mild-absorbing agent? The nitrogen atoms sponge up blue mild and make stones appear various degrees of yellow. These diamonds are categorized as 1A and judged for shade using scales: cape and canary.
Cape diamonds (a term adopted after the influx of yellowish diamonds from South Africa’s Cape province within the past due 19th century) are those maximum humans purchases. These are diamonds graded anywhere from barely to noticeably yellowish on the arena-famous GIA D-to-Z color-grading scale, starting kind of at K-colour. For years, cape diamonds have been considered much less suitable and thus used less in jewelry.
Then, around the flip of the 21 century, something momentous occurred that gave many cape diamonds a second life as regular canary diamonds: yellow diamonds of beautiful coloration on a special coloration-depth scale from light and pastel to bright and burning.
Unlike cape diamonds which are graded for the absence of color on a D (colorless) to Z (tinted) scale, those stones are rated for the presence of shade, the use of a 5-level revolutionary level, also developed with the aid of GIA: 1) fancy mild, 2) fancy, 3) fancy excessive, 4) fancy vibrant, and five) fancy deep. Instead of reducing these stones into traditional noticeably extraordinary rounds whose glare reduces yellow tint, dealers started out slicing them as exceedingly refractive square and square cuts. Suddenly, stones as soon as considered much less appropriate colorless diamonds had second acts as full-fledged fancy colored diamonds. This innovation allowed lots of undesirable cape diamonds to turn out to be a great deal-desired canary.
Fancy Yellow Diamonds：A True Canary
Besides being a well-known term for all yellow diamonds that qualify as fancy coloration, the term canary has a selected meaning as an ideal yellow color.
This secondary which means has resulted in semantic confusion. Sadly, the canary has often been used as a superlative–a utilization it changed into never supposed to have. Although professionals might agree on the very few stones that merit description as top-of-the-totem canaries, they’re careful to pronounce only a few stones as worthy of this period. Almost on every occasion, when I have requested a colored diamond specialist to show me a stone that embodies his definition of actual canary. I was told they had no such stone and didn’t understand everybody who did.
I took my search for a real canary diamond to Alan Bronstein, a dealer who has amassed the 2 largest collections of fancy color diamonds in cutting-edge records, hoping he might display me the holy grail of fancy yellow diamonds. He confirmed me a stone that seemed as bright as a metal on an anvil—natural yellow with perhaps just a hint of orange. I can best describe this stone as a “fiery yellow diamond that glowed like a past due-afternoon sun,” and leave it at that. Suffice it to mention. I can now attest to the life of canary diamonds as stunning as any chicken of paradise.
Also suffice it to say, authentic canary diamonds are spotted approximately as seldom as grails and unicorns. Such stones are stratospherically highly-priced.
Nevertheless, there’s a complete spectrum of quite simply to be had, very inexpensive fancy yellow diamonds–thanks to the advent of the radiant reduce.
Fancy Yellow Diamonds：Splendors Galore
For years, cutters have contemplated the problem of retaining the diamond’s fabled brilliance at the same time as on the equal time heightening color.
Their answer became very similar to the only George Kunz devised to maximize, in preference to cut, coloration in rough. But modern cutters departed from Kunz via inventing a hybrid that balanced the fine factors of the cutting-edge-first-rate and rectangular-to-rectangular shaped cuts. This worried cutting strongly yellowish cape stones with the bottom of a present-day changed superb and the pinnacle of a square or square form. Square and rectangular tops made mild rays tour a greater distance inside the stone before being pondered to the eye. As mild paths lengthened, color refraction changed into strengthened. Greater refraction gave greater intensity and intensity of color. At the identical time, modern-day-first rate bottoms confident the fantastic glitter that one expects from diamonds.
Overnight, hundreds of unpleasant duckling diamonds were transformed into swans. Today, almost all fancy yellow diamonds are cut as radiants.
As a fashionable rule, these stones own the equal depth and intensity of shade as yellow sapphires–with the delivered bonuses of the diamond’s greater brilliance and hardness. No surprise, the proliferation of fancy-yellow radiant-cut diamonds has created a brand new thriving market for fancy-color yellow engagement and wedding ceremony diamonds. Slowly however virtually, the diamond is taking over as plenty popularity as a colored stone as a colorless one. As a result, increasingly brides are carrying fancy yellow diamonds. Some who love colorless and colored diamonds, wear each. Thanks to fancy yellow colors, the diamond has received a reputation as each a colored and colorless gemstone.
