About Quartz

Quartz is the second most common mineral in the crust of earth and is made from silicon dioxide or SIO2. 

Quartz: Crystal Kingdom of Earth’s Crust

Quartz is the second most abundant mineral in Earth’s continental crust and is composed of silicon dioxide (SiO₂)—the same tough, shiny mineral behind everything from sand to semiconductors.

Quartz shows up in two main forms: macrocrystalline (the classic crystals we think of when we hear “quartz”) and microcrystalline (the tightly packed version that makes agate, jasper, and chalcedony).

When quartz grows with visible crystal faces, we call it macrocrystalline or euhedral quartz—these are your familiar points, clusters, and towers. But when it spreads out in a dense mosaic of tightly packed crystal bits, it becomes massive quartz—a solid, less sparkly but no less powerful form.

Quartz druzy refers to a surface coated in tiny quartz crystals—like sugar crusted over stone. Druzy can be big or small, but always has that sparkly, crystalline shimmer on the surface.

Quartz also forms as cryptocrystalline or microcrystalline, where the crystal structure is only visible under high magnification. This includes a vast family of materials: agate, jasper, chalcedony, chert, and more.
