Tourmalated Quartz
The Shield of Light
Also known as: Tourmalinated Quartz
About the stone

Clear to milky quartz with Black Tourmaline inclusions. These inclusions are solid black, needle-like inclusions and can be sparse or dense, entirely inside the quartz, or protruding from & encompassing the quartz. They can be dense enough to make the quartz appear almost entirely black. They differ from Rutile in that the needles tend to be thicker and blunt on the ends.

Care and handling
Tourmalated Quartz is hard and durable, but the needles can create planes of weakness, so avoid hard knocks and drops. Clean with lukewarm water, mild soap, and a soft cloth, then dry well. Avoid ultrasonic cleaners and steam for heavily included pieces, and avoid sudden temperature changes. Keep polished pieces away from harder stones that could scratch them.
Individual experiences with Tourmalated Quartz vary, and it is a symbol of balance rather than a guarantee of protection. Use it as a focus for clear boundaries and honest self-reflection.
