Black Opal Tanzanite Jewelry

Black Opal Tanzanite JewelryBlack opal tanzanite jewelry can look very distinctive when designed well and with the right clothes or in the right setting.

Tanzanite is the blue/purple variety of the mineral zoisite discovered in the Meralani Hills of Northern Tanzania in 1967, near the city of Arusha. Hence the name. It is a popular and valuable gemstone when cut, although not as durable as many other gemstones as it has a tendency to break if treated roughly. It’s inclination to break tends to preclude its use as a ring stone. Tanzanite is noted for its remarkably strong ability to appear alternately sapphire blue, violet, and sage-green depending on crystal orientation. Most tanzanite is subjected to artificial heat treatment to improve its colour however, and this significantly subdues this ability.

Australian black opals are considered the most valuable of all the opals. They are found in one place only, Lightening Ridge in northern New South Wales. Millions of dollars of black opals have been found in Lightning Ridge and it is quite likely that millions more will be found also.

A black opal color can range from dark gray to jet black but this does not refer to the spectral colors in the opal, rather to the general body tone. The spectral colors can still be seen in the depths of the opal and can look even more striking due to the dark tone of the opal .

A combination of black opal and tanzanite can make a very nice broach or even necklace. Rings tend to be disfavored due to the brittleness of the tanzanite and the rougher treatment rings get more than other jewelry.

Nevertheless, a black opal tanzanite jewelry ring can look very striking and, provided great care is taken when using it, will enhance the appearance of any hand.
