This Spring, Sotheby's presents a sixth entry into this elite asset class, a classic emerald-cut estimated to sell for between $28 - $35 million, giving it a $190,000 per carat valuation.

The original rough stone –weighing over 200 carats – was mined by De Beers in South Africa within the past ten years and is brand new to the market.

Gary Schuler, head of Sotheby's Jewelry "The color is whiter than white…so transparent I can only compare it to a pool of icy water."

In 2013, Christie's sold a 101.73 carat, pear-shaped, D-color, flawless, sold for $26.7 million – or $262,830 per carat. The buyer was Swatch Group's Harry Winston division, which dubbed the gem, "The Winston Legacy."

The appetite for the world's most beautiful gems continues, according to Rahul Kadakia, international head of Christie's Jewelry.

"Just as a great artist is able to 'see' a masterpiece in a block of marble, a perfect diamond is the result of the skill and vision of a master cutter who is able to uncover beauty from a rough gem. Harry Winston acquired the most perfect diamond ever offered for sale at auction. 'Winston Legacy continues the tradition of buying and selling only the very best."

Sotheby's Hong Kong continues to holds the world record for this asset class, a 118.28 carat oval brilliant cut D-color, flawless, which sold for $30.6 million dollars to an anonymous buyer.

"The market white diamonds, have held and steadily exceeded their value for decades," says Sotheby's Darrell Rocha. "Buyers know their money is parked in a safe haven right here. For the price of a mid-size luxury condo in Manhattan, you can have an investment and an object to wear and admire for years to come."
