1 pcs Multicolour Sapphire - 3.17 ct - International Gemological Institute (IGI) - "Colour Change Sapphire"

This multicolor sapphire, weighing 3.17 carats and certified by the International Gemological Institute (IGI), is a fascinating example of a color-change sapphire. Such gems exhibit different colors under various lighting conditions, a phenomenon caused by the interaction of trace elements within the crystal lattice with light. Sapphires, primarily composed of corundum, are generally known for their blue varieties, but they also come in a spectrum of colors including pink, yellow, green, and multicolor. Color-change sapphires are rarer and highly valued for their unique optical effects, often shifting colors from blue to purple or from green to gray. Originating mainly from regions like Sri Lanka and Madagascar, these sapphires have been treasured in fine jewelry for centuries, appreciated for their durability, brilliance, and natural beauty.
