Chrome tourmaline is a rare and highly prized variety of tourmaline found primarily in East Africa, particularly in Tanzania and Kenya. This stunning gemstone is known for its rich green color, which is due to the presence of chromium and vanadium, the same elements that give emeralds their vibrant hue. Unlike other green tourmalines, chrome tourmaline exhibits a more intense and pure green, often with exceptional clarity and brilliance.
The discovery of chrome tourmaline in East Africa dates back to the 1960s. Since then, these gems have gained popularity among collectors and jewelry enthusiasts due to their unique color and high refractive index, which enhances their sparkle. The finest specimens display a deep forest green with excellent transparency, making them a sought-after choice for fine jewelry.
Mining operations in Tanzania and Kenya are relatively small-scale, often carried out by local artisanal miners. These deposits produce limited quantities, which adds to the rarity and value of chrome tourmaline. The gemstones are usually cut into faceted shapes to maximize their brilliance, and their durability makes them suitable for various types of jewelry, including rings, earrings, and pendants.
Chrome tourmaline is often compared to tsavorite garnet and emerald due to its similar coloration. However, it is generally more affordable than emerald and offers superior clarity compared to many tsavorites. With its vivid green hue and rarity, chrome tourmaline continues to captivate gem lovers and remains a prized gemstone in the world of fine jewelry.
