Tanzanite Gemstone

Tanzanite is one of the world’s rarest and most beautiful gemstones, found only in the Merelani Hills of Tanzania, near Mount Kilimanjaro. This extraordinary stone is a variety of the mineral zoisite and is highly valued for its mesmerizing blue to violet color.

Color

Tanzanite is famous for its rich violet-blue to deep royal blue color. High-quality stones display intense saturation and brilliance. One of its most unique properties is trichroism, meaning it can show blue, violet, and burgundy tones when viewed from different angles.

Treatment

Most Tanzanite gemstones are heat-treated, which is a standard and permanent treatment to enhance the natural blue-violet color. Untreated stones are extremely rare.

Hardness & Durability

• Suitable for pendants, earrings, and occasional-wear rings.

• Requires proper care to avoid scratches or hard impacts.

Origin

Exclusively mined in Tanzania, making it a true “one-location gemstone.” Its limited supply increases its rarity and long-term value.
