One of the many members of the quartz family, smoky quartz is the light brown to nearly black variety of crystalline quartz. Typically found at higher elevations, this quartz gets its smoky color from natural radiation caused by gamma rays. Metaphysically, smoky quartz is used for grounding. Fine specimens of smoky quartz are found in Brazil, USA, Switzerland, and Africa.
Rutile is a form of titanium oxide that creates slender, prismatic crystals. They form both alone and as inclusions within other minerals including quartz, ruby, and sapphire. This mineral commonly ranges in color from red to brown, but can also be pale golden yellow as it is found within quartz. Rutile-included quartz, for example, is called rutilated quartz and has been used as an ornamental stone since ancient times. Rutile can be found in such U.S. localities as Georgia, Arkansas, and California. Metaphysically, rutile is a great stabilizer for relationships of all kinds by creating emotional fidelity and grounding.
