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.
