Colored diamonds are attractive to investors because they are extremely rare, with only one carat being naturally colored out of every 10,000 carat extracted. The colored diamond market has grown significantly over the last few decades into a prominent global collectible market due to both the low supply and steady increases in demand. Examples show the value of colored diamonds like a one-carat pink diamond increasing from $10,000-$15,000 per carat 30 years ago to $330,000 per carat in 2013, and their price is expected to continue increasing given their rarity, beauty, and investment potential.
