The second of December’s birthstones is Tanzanite.
Tanzanite is a
comparatively new stone in gemmology because it was just found in the 1960s in Tanzania. It is found only in a small area of Tanzania. The
American Gem Trade Association nominated it as a December’s birthstone in 2002 when
it was recognized as a powerful violet flame crystal which facilitates healing
and transformation.
Tanzanite crystals possess a high vibration level which
makes them very precious stones for metaphysical healing. It promotes the development
of psychic powers and accelerated
spiritual growth. Tanzanite is believed to have mellowing properties and
provide balance in busy, stressful lives.
Although tanzanite is valued for its deep violet-blue
color, the fact is that it in reality it has to be heat treated to bring out
the blue violet of the natural stone. The
color varies from blue to purple, but the most valuable tanzanites are medium
dark in tone, vivid in saturation, and slightly violet blue.
Tanzanite is renowned for its tendency to trichroism. This
means it looks sapphire blue, violet or burgundy depending on the crystal
orientation. Natural tanzanite is a reddish brown in its untreated state and is very
rare.
Tanzanite was first used as a more affordable sapphire
substitute, but it has grown in popularity and now valued for its own beauty
and brilliance. It makes fabulous affordable jewellery and is perfect for
gifts.
It is interesting to note that TURQUOISE, the oldest
gemstone known and TANZANITE the youngest, are both December’s birthstones.
