Fancy Colored Diamond
Diamonds come in all different colors. The rarest is red and it can fetch bids well beyond the 1 million USD per carat threshold. Other rare hues include pink, blue, green, and orange and can also be sold for top dollar. Those of the yellow variety are similarly valued to colorless diamonds while brown, gray, white, and black mainly cover the mid-range market. Color is the most important factors in evaluating any non-colorless diamond.
