Red diamonds are the pinnacle of rarity in the colored diamond market, with stones selling for over $1 million per carat. It is rumored there are less than fifty pure red diamonds ever certified by the GIA, although that was said a few years ago. Red diamonds only come from a select group of mine and in any given year we will only see three to five red and purplish red diamonds come onto the market. Dealers and private investors are the most predominant buyers of these rare and attractive diamonds.
The spectrum of color tone for red diamonds is small, limited in both lightness and saturation. Recognized names for different mixtures of red are apple, burgundy, cherry, raspberry, rose, ruby, and strawberry.
