Quartz Points

You will receive one of the exact crystals shown. Some have rainbows, multiple terminations or clusters. Second most abundant mineral in the earths crust. It is a crystalline form of silicon dioxide (Silicon and oxygen). Form in either ingenious rock or environments with geothermal waters. Macrocrystalline quartz basically forms in three geological environments: in silica-rich molten rock during cooling and solidification in pegmatites during and following pneumatolytic processes in mostly watery solutions of silica under various conditions In these environments individual crystals grow by adding molecules at their surface, layer by layer Quartz is usually the last mineral to crystalize, and it typically fills in the spaces between other minerals and rock formations. In ingenious rocks quartz forms as magma cools. Silicon dioxide crystalizes as it cools. Slow cooling generally allows the crystals to grow larger. Forms in open cavities in rocks and deep within the earth. Whe
