Last week, the Archduke Joseph Diamond was sold for a whopping 20m Swiss francs (that's £13m or $21m!) at Christie's Auction House in Geneva!
An anonymous bidder bought the giant stone, after being lovingly kept by Alfredo Molina, the chairman of a Californian-based jeweller, for several years.
The diamond is thought to be over 400 years old and is named after an Austrian prince who it once belonged to. It originates from the famous Golconda diamond mines in India, where other such treasures such as the Koh-i-Noor diamond and the stunning blue Hope Diamond also came from.
The cushion-cut Archduke Joseph Diamond weighs a staggering 76.02 carats, has Internally Flawless clarity and is graded D in colour - meaning it is regarded as being a 'perfect' diamond and it is one of the most admired diamonds in the World!
