45 Carat yellow diamond could fetch $3.5m

A 45.07 carat fancy vivid yellow diamond is forecast to sell for $2.8m to $3.5m at Phillips New York on Wednesday (12 June).

It leads the New York Jewels Auction, featuring colored diamonds and gemstones, period jewelry, and signed jewels by Cartier, Bulgari, and Van Cleef & Arpels.

The square emerald-cut VS1-clarity stone has classic step-cut faceting, considered an unusual choice to best show off the color and draw out the illusion of greater saturation.

The Fancy Color Research Foundation (FCRF) gives the diamond a total visual score of 11 out of 12, based on inner grade (3), color dispersion (4) and undertone (4), noting that despite its depth percentage, excellent polish and symmetry grades, its visual presence translates to “a diamond appearing smaller in carat weight”.

The diamond will realize $77,657 per carat if it hits its high estimate. In March a 15.51-carat VS2 fancy vivid yellow diamond sold for $1.14m – $73,253 per carat – at Phillips Hong Kong Jewels Auction, beating its low estimate.

135ct Yellow Diamond

Gem Diamonds has recovered a 135 carat yellow at its Letšeng mine in Lesotho, the third significant colored-diamond discovery at the deposit this year.

The company retrieved the high quality, type I stone on June 21, three months after the mine yielded a similar quality yellow diamond weighing 134 carats. Those discoveries follow a two year gap in the recovery of yellow diamonds weighing more than 100 carats from Letšeng. In June 2017, the miner found a 151.52 carat yellow.
