No reserve price - 1 pcs Blue, Violet Tanzanite - 2.33 ct - International Gemological Institute (IGI)

Tanzanite is a rare and captivating gemstone prized for its vibrant blue to violet hues. It was discovered relatively recently in the Mererani Hills of northern Tanzania, which remains the only known source. This gem is a variety of the mineral zoisite and owes its unique coloration to trace amounts of vanadium. The spectrum of colors shifting between blue and violet depends on the angle of viewing and lighting conditions, making each stone visually dynamic and desirable. Tanzanite's relative softness compared to diamonds or sapphires means it is often reserved for pendants or earrings but can be worn as a ring with proper care. Graded by reputable gemological labs like the International Gemological Institute (IGI), such stones come with certificates verifying their quality and authenticity, providing assurance to collectors and buyers. Because it is scarce and newly introduced to the market, tanzanite is prized as a collector's gem and used extensively in fine jewelry.
