As part of the tanzanite buying guide, we are going to show you how to take care of the precious gemstone. Unlike diamond, Tanzanite is a softer gemstone (similar to Emerald). It makes some of the most stunning jewelry, but it does need to be handled with a little more care than you would with Diamond.
Avoid any ultrasonic cleaning (often used by jewelers to clean jewelry), as this can cause the stone to crack or shatter. Also, avoid jewelry cleaner(s) as this is far too harsh for the stone.
Instead, use warm soapy water and a soft brush (a toothbrush is ideal) and gently clean the stone, paying attention to the underside where it is mounted into the gold, silver or platinum. Once clean, dry it with a soft cloth.
