Blue Diamond

Blue diamonds are the most valuable gemstones in the world. They are not only uncommon, but they also have a magnificent shine.

The diamond, named “The Oppenheimer Blue” after its former owner, sold for 57.5 million. While the Pink Star diamond set a new record for the most costly gem ever sold, the blue diamond has the highest price per carat at 3.93 million. They are also used to engrave expensive watches.

An extremely rare Burmese ruby was auctioned off for more than $30 million at a Sotheby’s event in Geneva in 2015. This means that the 26-carat diamond, dubbed “The Sunrise Ruby” after a poem by Rumi, the famed 13th-century poet, sold for $1.18 million per carat. That is an incredible sum, making it the most costly ruby ever sold. But not all rubies are priced the same, as depending upon the quality of the stone, typically it starts from 20,000 and goes up to hundreds of thousands and even millions.

It was thereafter passed down to their son and subsequently privately sold. It was acquired at Christie’s for $5.5 million, or $305,000 per carat. As a result, it was the most costly emerald per carat ever sold.

The more iron there is in the grandidierite, the bluer it is.

Grandidierite is an exceptionally hard gemstone, with a Mohs hardness grade of 7.5. As a result, it is a tough gemstone that may be used in a number of jewelry applications. Grandidierite is a highly valued gemstone due to its rarity and beauty. The average price per carat for grandidierite is €17,295 ($20,000). However, high-quality materials can sell for much more than this.
