One fascinating fact about bi-color sapphires is the unique geological conditions required for their formation. Bi-color sapphires are formed when different trace elements are introduced into the crystal structure of the sapphire during its growth process. These elements create distinct color zones within the same gemstone, resulting in captivating color combinations. The precise combination of trace elements and the conditions under which they interact determine the colors and patterns exhibited by the bi-color sapphire. This geological rarity adds to the allure of bi-color sapphires, making them highly prized among gemstone enthusiasts for their exceptional beauty and uniqueness.
