Tourmalinated Quartz

2 months ago 128 Views

Tourmalinated quartz gets its name from the needle-like crystals of black tourmaline found within the quartz. Extremely high temperatures and pressure caused the two minerals to liquefy and mix together. Upon cooling the tourmaline crystalized within the gradually hardened quartz, forming the unique black needle inclusions. Most tourmalinated quartz is mined in Minas Gerais, Brazil, but can be found in many parts of the world.
