Physical properties

Hardness: 6-6.5 on Mohs scale; Color: Pale green to turquoise blue-green; Luster: Vitreous to pearly; Crystal structure: Triclinic; Cleavage: Perfect in two directions; Specific Gravity: 2.56-2.58.

Formation & geological history

Formed in plutonic rocks, specifically pegmatites and granites, through hydrothermal activity. The characteristic green color is believed to result from small amounts of lead and water within the feldspar structure.

Uses & applications

Primarily used as a gemstone for jewelry (cabochons, beads), decorative carvings, and in the metaphysical/crystal healing industry. These specific chips are commonly used for 'spell jars', resin art, or aquarium decor.

Geological facts

Also known as 'Amazon Stone', it was named after the Amazon River, although no deposits have actually been found there. Historically, it was used by Egyptians to make jewelry and was found among the treasures of King Tutankhamun.

Field identification & locations

Identify by its distinctive 'schiller' or grid-like white mottling/streaking across the green surface. Commonly found in Brazil, Russia (Ilmen Mountains), and the USA (Colorado and Virginia). Collectors look for deep saturation of blue-green colors.
