Known as being one of the most stunning gems within East Africa, Tanzanite Gemstones come in a variety of velvety blue colors, with some even including more of a purple tone. First found in 1967, the Tanzanite gemstone name came from its origination, Tanzania. Put out into the world market in 1969, the actual color of these loose Tanzanite gems is always a brownish color. It isn't until it is heat treated that it turns the color blue or purple.

A History on our Loose Tanzanite Gems
The name Tanzanite is derived from Tanzania, which is located in eastern African. This is only place that this December birthstone can be found. Tanzanite gemstones were first discovered in the year 1967. It has been called the "gemstone of the 20th century" and has been made quite popular by Tiffany's in New York City. When the first glimpse of these semi precious gem stones were seen, specifically discovered in the northern Merelani Hills of Tanzania near Arusha, it was quite a sight.
What Are These Semi Precious Gem Stones Made of?
Tanzanite is comprised of calcium aluminum silicate and is a blue variety of zoisite, a semi precious gem stone. Its value on the Mohs scale is between 6.5 and 7, which means that it is more delicate than other semi precious gem stones and should be worn carefully. It should never come into contact with any acids or be placed in ultrasonic cleansing bath. The name Tanzanite was actually suggested by the Tiffany jewelry company, rather than its formal name "blue zoisite," due to the fact that "zoisite" is too similar to the word suicide.
Offering a broad range of color from light violet-blue to ultramarine blue, this gemstone looks beautiful in larger sizes. Sometimes one may notice a tint of brownish-yellow, which occurs in more raw stones than any other. This can be diminished by heating the gem over 500 degrees, but one must be experienced and careful not to heat the gem too much, which will ruin its natural beauty. This particular gemstone can be cut into various shapes and sizes and ranges in price. The price tag associated with the stone may seem steep to some, but it's because of the fact that loose Tanzanite gems only come from one place in the world.
