Tourmalinated Quartz Moon

A hand-cut tourmalinated quartz moon from Brazil with clear quartz and embedded black schorl crystals, a documented collector's material.

Tourmalinated quartz forms when needle-shaped schorl crystals (NaFe₃Al₆(BO₃)₃Si₆O₁₈(OH)₄) are enclosed during quartz growth. This inclusion geometry is typical in the pegmatite context and indicates a two-mineral genesis.

The moon shape was cut from natural rough material and polished all around. Each piece is a natural product with an individual schorl pattern.

Brazil supplies the world's most important tourmalinated quartz material of this quality, with evenly distributed, sharply delineated black needles in a clear quartz background.
