Lost in the news surrounding the record-breaking auction sales of the diamonds “The Pink Star” and “The Orange”, a little red gem also made broke records this week.
At Christie’s auction in Geneva on Tuesday, a 1.92-carat fancy red diamond sold for more than 3.25 million, the most ever paid at auction for a red diamond. The early word on the stone was that would sell between $2 – $3 million, so the final figure was considered a surprise.
Red diamonds are considered the most rare of all colour diamonds and are caused by a specific structure of the atoms within the diamond. If this structure produces what are called grain lines, the diamond appears red. The more the lines, the deeper the colour. The deeper the colour, the more rare the stone.
The most famous red diamond in history is the 5.11 carat Moussaieff Red Diamond. It is considered the world’s largest red diamond and was found by a Brazilian farmer in the Abaetezinho River in 1990. As a rough stone, it weight 13.9 carats. After being purchased and cut by the William Goldberg Diamond Corporation, It was then bought in the early 2000s by Shlomo Moussaieff for an undisclosed price.
