Even experienced gem cutters find it a challenge with rough tourmaline crystals. Multi-colored gemstones are often weak at the point where the color meet, but every variety may have stressed zones. Once the tourmaline rough is cut and set, it makes for durable jewelry.
It has a Mohs hardness of 7 to 7.5, meaning it can resist scratches from everyday hazards, including household dust. This means anyone can wear a tourmaline gem for any occasion. Because of their electric conducting properties, tourmalines will attract more dust than other non-conductive gems, therefore their hardness is a point to their advantage. But this tendency to attract more dust also means they will need more frequent cleaning.
Because most tourmalines have several inclusions, you must avoid ultrasonic cleaning or using steam devices to avoid change in the gemstone. The vibrations and heat can cause liquid inclusions to expand and shatter the stone. The best way to clean your gemstone is with a soft brush, and warm soapy water, using a mild detergent.
