1 pcs Green, Yellow Tourmaline - 6.35 ct - International Gemological Institute (IGI)

Tourmaline is a highly prized gemstone known for its wide range of colors, often found in striking bi-color or multi-color specimens. The green and yellow tourmaline featured here is an excellent example of this diversity, showcasing a blend of vibrant hues that are both eye-catching and unique. Tourmaline crystals form in igneous and metamorphic rocks when boron interacts with elements like aluminum and iron, resulting in complex chemistry that creates its vivid colors. This particular gem, certified by the International Gemological Institute (IGI), assures quality and authenticity, making it a coveted piece for collectors and jewelry enthusiasts alike. Beyond its beauty, tourmaline is durable enough for various jewelry uses, and its color variations inspire many cutting styles to enhance its natural brilliance.
