The name Tanzanite is derived from Tanzania, which is located in eastern African. This is only place that this December birthstone can be found, and it was 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 this brilliant blue stone with purple tones was seen, specifically discovered in the northern Merelani Hills of Tanzania near Arusha, it was quite a sight.

Metamorphic schists, quartzites and gneisses had formed flat topped inselbergs millions of years ago on the plain that was shadowed by Mount Kilimanjaro. The crystal continued to grow inside of these inselbergs for a very long time before they were ever spotted by man. Now in the Merelani Hills, there are numerous small mines where many small grains of Tanzanite are found.

Tanzanite is comprised of calcium aluminum silicate and is a blue variety of zoisite, a gemstone. Its value on the Mohs scale is between 6.5 and 7, which means that it is more delicate than other gemstones 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 Tanzanite stones only come from one place in the world.
