Tanzanite
Tanzanite is a very special and unique gemstone. World-wide
it occurs only in one specific location, the east-African
state of Tanzania. After its discovery in 1967, Tanzanite
was enthusiastically celebrated as "Gemstone of the 20th
Century".
Spectacular and magnificent is the hue of Tanzanite, ranging
from ultramarine to a light purplish blue. The most coveted
colour is a deep blue which shows a purplish hue shimmering
around it. Typical for Tanzanite is the appearance of several
colours in one and the same stone: depending on the perspective,
the stone appears blue, purple, or dun yellow. This rare and
beautiful gemstone symbolizes immaculate elegance for those
of discerning tastes.
Tanzanite achieves only hardness 6.5 to 7 on the Moh's
scale, and is thus not very resistant. Therefore it should
be worn with care, never be cleaned by ultrasonic method
and never come into contact with acids.
