A rare Golconda diamond to go under the hammer at Sotheby’s

Sometimes I feel places like Sotheby’s are doing a special service to the opulent. They keep ensuring that the rich keep getting rare things at obscene rates. Another rare gem (quietly literally) which is an emerald-style cut diamond, of 52.82 carats, is up for auction at the Sotheby’s Geneva Spring 2010 sale of Magnificent and Noble Jewels. Rated as a D flawless stone and evaluated as type IIa diamond, these diamonds are popularly known as Golconda diamonds too. The rare stone is touted to fetch over $7 million.
