A German gemologist and mineralogist, Friedrich Mohs introduced an instrument designed to rate gems on a scale of 1-10. The rating is determined by the measure of scratch resistance against other minerals. Diamonds top the charts at 10 on the Mohs hardness scale, while Talc rates the lowest at 1; tanzanite is rated between 6.5 and 7.
Cleaning and care
Jewelry should be cleaned periodically .Tanzanite should not be exposed to hydrochloric and hydrofluoric acids as they tend to damage the stone. The best way to maintain tanzanite jewelry is to clean it with a little soap and warm water. Steam cleaning or ultrasonic cleaning methods expose the gemstone to high heat and frequency vibrations that can, again adversely affect the cleavage of the gemstone.

A great example of keeping the gemstone protected, in regard to jewelry, can be seen in our Purvi tanzanite bracelet that has the gem beautifully enclosed in a bezel setting. The case-like design offers some protection for the gemstone from some abrasion, while fastening it securely to the metal.
The gemstone does have a fair resistance to breakage, but is prone to scratches, hence, it’s recommended it be worn on special occasions. Of course, when you have luxurious designs like our 8.85 CT tanzanite earrings, in 14-carat white gold, it’s an easy decision. The timeless design, featuring diamonds surrounding the violetish-blue gemstone, emphasizes the beauty of each earring and makes them quite the eye-catchers.
Tanzanite is Trichroic, post heating - showcases three different colors, deep royal blue, bluish-purple, and a slight reddish shade. This means, according to the Mohs scale, tanzanite is not affected at permissible temperatures. However, the gemstone could break on surpassing them as it possesses a single cleavage, making the gemstone prone to abrasions.
Inclusions are minerals that are crystalized while the gemstone is being formed. These minerals add to the gemstone’s strength. One can easily spot these attributes in this fantastic 1.74 CT oval tanzanite ring from our collection.
Lesser known fact - Though the Mohs scale is used as a yardstick to determine the strength of a gemstone, the score of each individual gem is subject to change, based on mineral inclusions that form, as part of the formation process.
