lady luckA fancy vivid yellow diamond weighing a whopping 77.77 carats is expected to be the top lot at Sotheby’s Hong Kong, with a pre-sale estimate up to $7.7 million.

Clearly the top lot has auspicious ties to the number seven. In the Western world, seven is considered the luckiest of all numbers; many a gambler has dreamed of hitting the 7-7-7 slot machine jackpot. For potential Asian buyers, seven is a lucky number that signifies togetherness, and the yellow hue is also symbolic of royalty and power.

The “Lady Luck Diamond” boasts a VS2 clarity and a pure fancy vivid yellow, the most desirable saturation for colored diamonds. Pure yellow diamonds owe their coloration to nitrogen atoms dispersed throughout the crystal matrix, which is extremely hard to penetrate. The amount of nitrogen present determines a yellow diamond’s saturation level, which is why the more intensely saturated gems are extremely rare and valuable.

Flanked by five-carat heart-shaped diamonds on either side, the “Lady Luck” is presented as the lady luck 2centerpiece of a three-stone ring in rich 18 karat yellow gold. It can also be detached and worn as a pendant on its own.

The “Lady Luck” is sure to appeal to a wide audience of bidders later this month at Sotheby’s “Magnificent Jewels and Jadeite Sale” at the Hong Kong Convention and Exhibition Center. The auction comprises 320 lots in total, including rare colorless and colored diamonds, gemstones, and signed pieces from the Art Deco period. Total sales expected to be generated are over $100 million.

A 6.13-carat fancy intense green diamond set a new per-carat record when it sold at Christie’s on May 27 for a whopping $3.6 million, or $594,510 per carat. The square cushion cut diamond is the center of a rose gold halo style ring, accentuated by natural pink diamonds.

Next to red, green is the rarest of colors found in natural diamonds. For most colored diamonds, the color comes from trace amounts of mineral impurities or extreme pressure conditions while the diamond was forming. The tight chemical structure makes it very difficult for any impurities to enter, which is why colored diamonds are exceedingly rare. Small amounts of boron in the crystal lattice structure of a diamond, for example, will impart a blue hue; same goes with nitrogen for yellow, and hydrogen for violet. What gives a diamond a green hue however, is the presence of natural radiation over millions of years. Because the radiation exposure is an external force rather than internal force (such as mineral impurities and lattice defects), it acts on the surface only. As a result, green diamonds are not green all the way through; the color is concentrated on the outer layers and tends to be weakly saturated. That is why a fancy intense green diamond, especially one of a size like this one, is almost a once-in-a-lifetime find.

This spectacular diamond joins the ranks of other recently sold, record-breaking gems at Christie’s. At their Geneva auction just last month, there were three record-breakers alone. They include ‘The Blue’, a fancy vivid blue pear shaped diamond weighing over 13 carats, a 76.5 carat light pink square-cut diamond that sold for $10.2 million, and the ‘Ocean Dream’ – a 5.5 carat, vivid blue-green diamond that went for $8.8million.
