Precise Explanation

Tanzanite's hardness and toughness are measured on the Mohs scale, which ranks minerals based on their relative ease or difficulty with scratching. However, the scale is not evenly spaced, and tanzanite's ranking of 6 to 7 can be misleading. While it may not be as hard as some other gemstones like sapphire, tanzanite still requires proper precautions against rough wear or hard blows. Its toughness is fair to poor, and it has a property called cleavage, which makes it prone to breaking when struck. Despite this, tanzanite can be worn in various jewelry styles with proper care.

Tanzanite's stability under normal conditions means it resists heat, light, and common chemicals. However, high temperatures or sudden temperature changes should be avoided, as they can cause damage. Exposure to hydrochloric and hydrofluoric acids can also harm tanzanite. When cleaning tanzanite, warm soapy water is always safe, but ultrasonic and steam cleaners are not recommended due to the risk of damage.
