A December birthstone, tanzanite is the recognized gift for the 24th wedding anniversary and also for the birth of a child-inspired by the native Maasai tradition of wearing blue beads and fabric for a healthy and positive new life. Tanzanite occurs in various colors including yellow, golden brown and green. It’s routinely enhanced by tradition heating methods to produce shades of violet blue to purple. Fine tanzanite is typically free of inclusions. No recent discovery has had a greater impact on the gemstone market than tanzanite. In 1967, a Portuguese prospector discovered tanzanite in Tanzania while looking for sapphire. Tanzanite quickly won the public’s heart.
