Tanzanite is a rare and highly sought-after gemstone that was first discovered in Tanzania in 1967. It is a blue to violet-blue variety of the mineral zoisite, and is known for its stunning color and exceptional clarity.
Tanzanite is often compared to sapphire or blue topaz, but its unique color range and rarity make it stand out from other gemstones. The most valuable tanzanite gems are a deep blue or violet-blue color, and are often used in high-end jewelry pieces.
