Dyed bamboo coral has replaced traditional coral in jewelry design due to red coral's depletion. Bamboo coral is not a protected coral species, as it is much more hearty and prevalent in the world’s oceans. (Named "bamboo" because its skeleton is made up of deeply calcified gorgonin – or horny – nodes. ) When harvested, it ranges in color from white to cream. Dakota Stones has enhanced it with a durable 3-step resin-and-oil process to colors that mimic those found in nature. The color, Living Coral, has been selected by Pantone as the 2019 Color of the Year.
