Tanzanite Rings

Tanzanite is a variety of the crystal Zoisite, and is one of the rarest precious stones available in the market today. Tanzanite was discovered in the year 1967 and was first found in the Meralani Hills of northern Tanzania. Tanzanite is mined exclusively under permit from the Tanzanian government and unlike other precious stones like diamonds, Tanzanite is found only in Tanzania. Although Tanzanite is used for a variety of jewelry, one of the most popular applications of Tanzanite is Tanzanite rings.

Tanzanite rings are available in a variety of finishes, and (like any precious stone) the cost of the rings varies depending on the size and quality of the stone. Below is a list of properties that makes Tanzanite unique: Trichroism Tanzanite is unique in that its color varies depending on the angle of light (called Trichroism). A typical Tanzanite crystal can vary from sapphire blue, violet, to sage-green depending on crystal orientation, and one of the first things buyers look for in a Tanzanite ring is the Trichroism exhibited by Tanzanite. Unfortunately, not all Tanzanite crystals are deep blue in color and most jewelers treat the crystal with heat to achieve the desired coloration. The only problem with heat treated Tanzanite crystals is that they loose their natural Trichroism to a certain extent. Rarity Tanzanite is only found in certain areas of Tanzania, no other precious stone in the world can make such a claim.

The Tanzanian government makes nearly $20 million annually from Tanzanite trade alone, and the resultant stones sell for close to $500 million in the jewelry market. Unfortunately, the rarity of Tanzanite has also fuelled speculation that its reserves might run out in the near future and there might not be another source of Tanzanite anywhere in the world. The rarity of Tanzanite has made it a sought after stone and a top quality Tanzanite gem can sell upwards of $500 per carat.

Exclusivity Contrary to popular belief, there are restrictions on the amount of Tanzanite that can be mined in a year and only a handful of companies and organizations have been given permission to mine in Tanzania. In a nutshell, unlike diamonds and other precious gemstones there is a limited amount of Tanzanite mined every year making Tanzanite one of the most exclusive gemstones available today. As mentioned earlier, there is speculation that Tanzanite deposits are rapidly depleting and fresh Tanzanite might not be available forever. Another factor that makes Tanzanite so special is that Tanzanite has a Mohs scale hardness of 6.5 (Diamond is a 10), making Tanzanite fragile when compared to other gemstones. It is not uncommon for Tanzanite to break on impact, and the relative softness of Tanzanite means that special attention has to be paid during the cutting and molding of raw Tanzanite crystals.

Like all precious stones the size and weight of Tanzanite is measured in carats and like diamonds, Tanzanite too has a clarity scale that determines the quality of the crystal after it is cut. Buying Tanzanite online Before buying Tanzanite online, it is important to look at the size, grading and quality of the gemstone. As mentioned earlier, top quality Tanzanite can sell for nearly $500 a carat and a Tanzanite ring with a 1 carat Tanzanite gemstone can cost upwards of $1000. It is important to read through the product description to understand not just the quality of Tanzanite being used, but also the quality of other materials used for making the ring. While buying Tanzanite rings, look for the overall weight of the Tanzanite gemstones used and also the quality of gold used. Keep in mind that there is more to a Tanzanite ring than just the Tanzanite gemstone and all factors must be taken into account when buying Tanzanite rings online.
