Hello my Darlings! Today I want to self-indulgently talk about one of the most elusive and beguiling minerals of the gemstone world; blue diamonds.
All colored diamonds can be breathtakingly beautiful and are also extremely rare. Blue diamonds are thought to be among the very rarest.
Owing to their regal and exquisite color and their rarity, blue diamonds have captured hearts and imaginations for centuries and as you can imagine, are extremely expensive. I remember when a blue diamond first captured my heart and imagination. Remember “the heart of the ocean” from Titanic? Who doesn’t? That stone actually turned out to be sapphire but to me it was a beautiful blue diamond.
The color in a diamond is actually an impurity or an additional element. In blue diamonds, it is traces of nitrogen and boron that cause their remarkable color.
The Wittelsbach-Graff Blue Diamond
This big blue beaut is also an old stone with a story. Originally a 35.5 carat stone, it originated from a mine in India. In 1644, King Philip IV of Spain gave the Diamond to his daughter as an engagement gift. The stone was passed down the royal bloodlines and in 1722 it became part of the Bavarian Crown Jewel collection. In 1931, a descendent of the last king sold the diamond at an auction in London and where it disappeared for nearly three quarters of a century. Laurence Graff acquired the diamond when it resurfaced in 2008 for the tidy sum of $24.3 million. He noted that the stone was full of flaws and marks and set out to have it restored. After careful work, the diamond lost a few carats. Now at only 31.6 carats it is the largest, internally flawless, deep blue diamond ever to be graded by the gemological institution of America.
Only about one or maybe two blue diamonds are found each year in the whole world. When they are found they make significant waves. Most diamond collectors can only dream of owning let alone ever seeing a blue diamond in person.
