Bi-color gemstones display two distinct colors within a single stone — a natural phenomenon that makes each one utterly unique. Browse our watermelon tourmalines, bi-color sapphires, and more.
Bi-color gemstones are nature's most dramatic expression of color variation — a single crystal containing two (or more) distinctly different hues. This phenomenon, caused by changes in trace element concentrations as the crystal grows, is most famously seen in watermelon tourmaline (pink core, green rind) and parti sapphires (yellow-blue combinations). Each bi-color stone is entirely unique.
