Tanzanite is the gem variety of the mineral zoisite and is a spectacular transparent blue. According to the book Gemmology by Peter Read, "In 1967, deposits of gem-quality transparent blue zoisite were discovered in Tanzania and given the name 'Tanzanite'.
These beads are, of course, lower grade tanzanite. Retail value of high quality tanzanite cut into faceted gemstones can be $1,000 per carat or more. Watch out for those funky drill holes! They're pretty rough.
