Diamonds have always been a symbol of wealth and luxury. Their unique beauty and rarity make them one of the most desired gemstones in the world. However, some diamonds are more rare and valuable than others. In this blog post, we will take a closer look at the most expensive diamonds in the world, their history, and what makes them so valuable.

1. Pink Star: A record-breaking gemstone

The Pink Star is a 59.60-carat pink diamond that was sold for $71.2 million at a Sotheby’s auction in Hong Kong in 2017. It is the most expensive diamond ever sold at auction. The diamond was mined in South Africa in 1999 and took two years to cut and polish. It was previously sold in 2013 for $83 million, but the buyer defaulted on the payment.

2. Oppenheimer Blue: A dazzling blue diamond

The Oppenheimer Blue is a 14.62-carat blue diamond that sold for $50.6 million at a Christie’s auction in Geneva in 2016. It was named after its previous owner, Sir Philip Oppenheimer, a member of the famous Oppenheimer family, who controlled De Beers, the largest diamond mining company in the world. The diamond was mined in South Africa and is set in a engagement ring alongside white diamonds.

3. Blue Moon of Josephine: A royal gemstone

The Blue Moon of Josephine is a 12.03-carat blue diamond that sold for $48.5 million at a Sotheby’s auction in Geneva in 2015. It was named after the daughter of King Gustav III of Sweden, Josephine of Leuchtenberg. The diamond was mined in South Africa and is set in a ring alongside white diamonds.

4. Graff Pink: A stunning pink diamond

The Graff Pink is a 24.78-carat pink diamond that sold for $46 million at a Sotheby’s auction in Geneva in 2010. It was previously owned by Harry Winston, who sold it to Laurence Graff, a British jeweler. The diamond is set in a ring and is surrounded by smaller pink and white diamonds.

What makes these diamonds so valuable?

The diamonds listed above are all incredibly rare and unique, which is what makes them so valuable. Diamonds are formed deep within the earth’s mantle and are brought to the surface through volcanic activity.

Only a small percentage of diamonds are gem-quality, and even fewer have the size and color to make them truly exceptional. Diamonds are also valued based on their clarity, cut, and carat weight. The clarity refers to the number and size of flaws in the diamond, while the cut refers to how well the diamond has been cut and polished. Carat weight, of course, refers to the size of the diamond.

Conclusion: A rare and beautiful investment

These diamonds are not only beautiful to look at; they are also valuable investments. For those lucky enough to own one of these rare gems, they represent a unique and enduring asset that will only increase in value over time. Whether it’s a rare pink diamond or a stunning blue diamond, these gems are truly a sight to behold.
