Description

Quartz Points – Medium

Quartz has a trigonal crystal system and is in the mineral class of oxides. It is formed in passages or hydrothermally in druses or clefts from a pure, silicic acid solution that contains no foreign substances.

Free-growing crystals can vary from long and slender prisms to crusts or ‘points’. There are usually six terminal faces that develop larger and smaller faces horizontally.

Quartz can occur almost anywhere. Veins formed in high temperatures are usually coarsely crystalized. When formed in low temperature veins, in geodes and sedimentary rocks, we enjoy the finer grained varieties. Clear quartz veins have been guides to miners to find gold in many regions for years.
