Tanzanite
Tanzanite is one of the newest gems on the market and was discovered only in 1967 in Tanzania. This lovely gem has been a worldwide success, and demand continues to exceed supply. Tanzanite is a variety of zoisite, which is a member of the epidote group. Colors include blue, purple and green. The most highly coveted color is a deep blue which shows a purple shimmer.

Tanzanite is trichroic and exhibits pronounced pleochroism. The colors respective to the three directions are sapphire-blue, sage green, and purple. Orientation is an important consideration for cutters who need to consider both the yield and the resulting color.

Tanzanite is indeed one of the most popular gems, frequently used in gemstone rings, engagement rings - centerstones and as tanzanite melee - and tanzanite is very-well suited for all other types of gemstone jewelry, including gemstone earrings, pins and brooches, as well as in necklaces and fine gemstone pendants.

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size
