Chemical Composition and Formation Process

Blue sandstone, often marketed as “Goldstone Glass,” is a man-made glass material that includes tiny, uniformly dispersed metallic crystals. Its chemical formula is primarily SiO₂ (silica) with copper and cobalt inclusions. The material is created by melting silica with metallic salts at high temperatures, then cooling it slowly to form a solid with a sparkling appearance.

Names and Alternative Names

The name “Goldstone” comes from the Italian “aventurina,” meaning “by chance,” referring to its accidental discovery. “Blue Sandstone” highlights its deep blue color and star-like glitter. Alternative names include “Monk’s Gold,” from the legend that it was discovered by Italian monks.

Mythology and Legends

Despite being a modern creation, blue sandstone is often marketed with metaphysical properties. It is believed to be a stone of ambition, confidence, and motivation. The legend of its discovery by monks adds to its mystical appeal, suggesting divine inspiration in its creation.

Electric Cosmology

Its glittering appearance is thought to symbolize the night sky, connecting it to cosmic energies and the vastness of the universe.

Mining, Production and Use

As a synthetic material, blue sandstone is produced in controlled environments rather than mined. The process involves melting silica with copper salts, then allowing it to cool slowly to achieve the desired crystalline sparkle. Blue sandstone is used primarily in jewelry, including beads, pendants, and decorative items, valued for its unique and cosmic appearance.
