Gemstones -- Tanzanite
The remarkable gemstone Tanzanite
was first discovered in 1962. It is mined in one place only,
Tanzania, under the shadow of the snow capped peaks of Mount
Kilimanjaro. It comes in a range of blues, from purplish blue
to violetish blue, and is most valued for the violetish or pure
blue color. Tanzanite is distinguished by its “pleochroism”,
meaning that if you look at the stone from different angles,
you are likely to see different shades of purple and blue. Many
gemstones are pleochroic, but do not display their pleochroism
in such an eye visible and compelling way. Tanzanite tends to
be vivid in color and free from inclusions. Tanzanite gemstones
are one of the most popular stones today, as they were when
they first became known in the market not that long ago.
