Red diamonds: the "holy grail" of colored diamonds

Red diamonds, often referred to as the "holy grail" of colored diamonds, are the epitome of rarity and exclusivity. Their mesmerizing crimson hues have captivated gem enthusiasts and collectors for centuries. These magnificent gems, with their intense red coloration, stand in a league of their own, commanding attention and admiration wherever they appear.
Red diamonds are exceptionally rare, and their scarcity is attributed to a combination of geological factors and the presence of a specific structural defect within the diamond lattice, known as "grain boundaries." These grain boundaries distort the way the diamond absorbs light, resulting in the stunning red coloration.
The rarity and allure of red diamonds have made them highly sought after in the world of auctions, where extraordinary gemstones fetch record-breaking prices. Let's explore some notable examples of red diamonds sold at auctions and the stories behind them:

    1. The Moussaieff Red Diamond: Weighing in at 5.11 carats, the Moussaieff Red Diamond is one of the largest red diamonds ever discovered. This rare gem was found in Brazil and is known for its exceptionally vivid red color. In 2001, it was purchased by the Moussaieff Jewelers for a staggering $8 million at an auction in Sotheby's. Today's estimated value of the stone is $20 million.

    2. The Hancock Red Diamond: This legendary diamond originated from the Golconda mines of India, renowned for producing some of the world's finest diamonds.

In 1987, the diamond was auctioned for $880,000 and sold for $927,000 with a 6500% profit for it's owner.
