Discovered in Tanzania in the mid-1960s, tanzanite is mined only in the large hilltop area where it was first found.
To honor its single-source availability, Tiffany & Co., which introduced tanzanite to the world in 1968, named it after its East African birthplace.
"Although the Tiffany & Co. connection gained the newcomer worldwide publicity, tanzanite has won international popularity on its own merits in the last decade," Hucker says.
Depending on whether it is cut to emphasize its blue or violet color component, tanzanite can resemble the finest royal-blue sapphire or hint at amethyst.
Such color versatility has endeared this member of the zoisite family to leading jewelry designers in America, Europe and Japan.
"Once tanzanite became a staple gem, and once supplies showed no sign of letting up, it seemed as worthy of membership on the birthstone list as aquamarine and sapphire, the birthstones for March and September," says Hucker.
