The past decade was a good one for those who invested in fancy colored diamonds. According to Fancy Color Research Foundation (FCRF), which last week published an analysis of the Fancy Color Diamond Index (FCDI) in 2019 and over the last decade. During the years 2010 to 2019 the general index showed a steady market price increase of 77 percent. 

Leading the index during the decade were fancy pink diamonds, which registered an increase in value of 116 percent. In contrast, the prices of fancy blue diamonds rose by 81 percent, the prices of fancy yellow diamonds by 21 percent.

Among the more specific results recorded over the past decade, in the the pink color category 5-carat stones rose in value by an average of 99 percent. In the blue color category, 1-carat fancy vivid blue diamonds increased in value by 135 percent, and in the yellow color category, fancy vivid yellow 5 caraters and 3 caraters increased by in value by 30 percent.

Looking specifically at 2019, there was a 1.4 percent decrease in FCRF’s general fancy color price index, mainly influenced by a 5.4 percent decrease in fancy yellow diamonds.  In contrast, the pink and blue categories showed stability. 

 “The declines we witnessed in 2019 in the fancy color index are a ripple effect caused by the double digit decrease in the colorless category in the last few years,” said FCRF Advisory Board member Jim Pounds. “From the mining perspective we are currently experiencing a shortage in high quality fancy color rough and we therefore feel quite optimistic about the future.”

In further detail, in the pink category, fancy vivid pink increased in value by 4.4 during the fourth quarter, while 3-carat sized fancy vivid pink increased by 9.1 percent. In the blue category, 1-carat, 1.5-carat  and 2-carat sized stones increased in value by by 2.5 percent, 3.7 percent and 2.7 percent respectively.
