This amazing gem is the Archduke Joseph Diamond, sold during a Christie's auction in Geneva, on Tuesday, November 13.

The 76.02 carat diamond went for a record breaking $21.5 million, (€16.86 million). Archduke Joseph August of Austria (1872-1962), of the Hungarian Habsburg dynasty, first owned the gem, which was found in the Indian Golconda mines, according to The Times of India.

"It is a world record for a Golconda diamond and a world record price per carat for a colorless diamond," Christie's director for the international sale of jewelry says. Two decades ago, it was auctioned off for half its current price.

In case you cannot tell from the photograph, this rock is enormous. It is roughly the size of a strawberry, colorless and it has been referred to as the "perfect diamond."

The Archduke Joseph was owned by Alfredo J Molina, from California's Black, Starr & Frost. Oddly, this year's buyer wished to remain anonymous, probably to avoid a record-breaking heist.
