Tanzanite:
Named for Tanzania, the country where the gemstone was first mined in 1967,
tanzanite is a relative newcomer to the gemstone kingdom. This exotic, vivid
stone has been found nowhere else on earth. Tanzanite is now an alternate
birthstone for December.
Tanzanite rates 6 1/2 on the Mohs scale of hardness.
Enhancements:
Although cutting is the most basic enhancement method necessary to display the
beauty of a gemstone, there are many fascinating methods by which man has
demonstrated his ability to draw maximum color, luster, clarity and brilliance
from nature's earthbound treasures. A basic understanding of these enhancement
techniques will add to your appreciation of the beauty, durability and value of
the
gemstone jewelry you already own,
or plan to purchase in the future. Virtually every
tanzanite is heated to
permanently change its color from orange-brown to the spectacular violet-blue
color for which this gemstone is known.
Buying a Tanzanite:
As with most gems, the most important factor is color!
Tanzanite ranges from lavender to
purple to nearly royal blue. The deeper, richer the color, with pink and red
flashes, the more desirable the gem. Tanzanite in sizes of 2 carats or more is
considered important.
Tanzanite is a relatively soft
stone, so if you plan to wear your piece of jewelry a lot, select a piece in
which the stone is protected (with a bezel or semi-bezel) or does not sit too
high off the finger.
Tanzanite care:
Do not use an ultrasonic cleaner. Avoid sudden temperature changes, steaming and
contact with cosmetics, hairspray, perfume or household chemicals. Clean only
with a damp cloth or soft brush with room temperature water.
