Blue diamonds are an alluring option for those seeking beauty and a value-holding investment. In fact, colored diamonds have shown significant appreciation over the last 20 years. Both jewelry collectors and investors alike have flocked to these colorful diamonds and when they come to auction, the price tag often sets records. Here are a few blue diamonds that have hauled in hefty price tags over the last few decades.
In 2015, the 12.03-carat ‘Blue Moon’ diamond was sold for over $48 million at auction. At $4 million per carat, the Blue Moon diamond is one of the most expensive diamond per carat ever sold. The diamond was discovered in 2014 at the Premier mine in South Africa and demonstrates the highest possible color grading for blue diamonds. This means that it is free of any inclusions or scratches. The Gemological Institute of America (GIA) has even labeled the Blue Moon Diamond as internally flawless, a perfect clarity grade.
