No reserve price Blue Tanzanite - 2.57 ct - International Colored Gemstone Association (ICA GemLab)

Blue tanzanite, weighing 2.57 carats and certified by the International Colored Gemstone Association (ICA GemLab), is a striking and relatively recent addition to the world of precious gemstones. Discovered only in Tanzania in the 1960s, tanzanite is a variety of the mineral zoisite and is prized for its vivid blue to violet-blue hues. Its pleochroic nature means it can show different colors when viewed from different angles, adding to its mystical appeal. Tanzanite has gained popularity for use in fine jewelry such as rings, earrings, and pendants, prized for its rarity and vibrant color. Certification ensures the gem’s natural origin, treatments, and grading details, important for buyer confidence. While somewhat softer than sapphires or diamonds, tanzanite remains a glamorous and coveted gemstone choice.
