Lapis lazuli is a gemstone with a hardness rating of 5 to 6 on the Mohs scale, which can vary depending on its composition. It’s a tough stone that can last for generations if cared for properly.

If your lapis lazuli jewelry or carvings have been dyed, the dye may come off if rubbed with acetone (nail polish remover) or denatured alcohol. To prevent this, some lapis lazuli items are sealed with wax or plastic. However, wax sealers can degrade when exposed to heat or solvents.

Lapis lazuli that hasn’t been dyed may be impregnated with wax or oil to improve its color and shine. These treatments aren’t very stable, and a gemologist can easily detect them.

To clean lapis lazuli, warm soapy water is the best option. However, it’s important to test a small, inconspicuous area first to ensure that any dye treatments are stable.
