Quartz Geode

Hardness of 7 on the Mohs scale, typically white or clear with a vitreous luster, forming hexagonal crystal structures.

Formed when mineral-rich groundwater deposits silica inside hollow cavities in sedimentary or volcanic rocks over millions of years.

Widely used in decorative items, jewelry, crystal collections, and industrial applications requiring pure silica.

Geodes appear as ordinary, unassuming rocks on the outside, but cracking them open reveals dazzling, sparkly crystal linings inside.

Identified by its outer nodular, bumpy exterior paired with an inner cavity lined with sparkling quartz crystals; found worldwide, notably in Brazil and Mexico.
