Why do we focus so much on Blue diamonds?

Blue diamonds are among the rarest of the Fancy diamonds—just after red diamonds. Some claim, based on their very high prices, that pink diamonds are more rare than blue, but that’s mostly due to increased demand rather than reduced supply.

Though often confused, sapphires are entirely different gemstones than blue diamonds. Sapphires are a member of the corundum family and contain traces of titanium, iron, magnesium, copper and chromium. The mesmerizing color of the blue diamond, on the other hand, comes from the presence of boron within the diamond’s mostly carbon composition.

Many blue diamonds are Type IIb diamonds, which account for only 0.1% of the world’s color diamonds.

Their level of rarity makes blue diamonds even more suitable for diamond collectors, investors and enthusiasts.

Blue diamonds belong to the family of Fancy Color Diamonds, the name for diamonds that exhibit a rich color. Assessing a blue diamond’s value is based on its 4Cs (Cut, Color, Clarity and Carat), with Color being the most important factor by far.

With the price of blue diamonds continuing to display incredible strength in the auction market, is it any wonder that the retail market for these blue gifts of nature is eternally vibrant? Although the blue diamonds that do make the headlines may sell for the tens of millions of dollars, there are smaller stones for sale that are more reasonably priced. These stones have excellent depth of market, liquidity, and investment potential.

Fancy intense blue diamonds exceeding 5 carats appreciated by 368% over the 12 year period from 1998 for an annualized return exceeding 30.5%. This time frame spans both the “Tech Wreck” of 2000/20001 and the GFC of 2008. Fancy intense blue diamonds of between 2-3 carats appreciated 1000% over the same period for an 83% annualized return.


In 1998, a 5.32ct, Fancy Intense Blue sold for USD285,000/carat

In 2007, a 5.04ct, Fancy Intense Blue sold for USD570,000/carat
