Polished Morganite (pink beryl), possibly rose quartz

Beryl, Be₃Al₂Si₆O₁₈, colored by manganese; visual identification is uncertain because the image is blurred

AI-generated identification · may be incorrect

Pale pink to mauve, translucent, and highly polished with a vitreous luster; beryl has Mohs hardness 7.5–8, hexagonal crystals, poor cleavage, and specific gravity about 2.7. Rose quartz is softer (Mohs 7), typically cloudy, and lacks visible crystal faces.

Physical properties

Pale pink to mauve, translucent, and highly polished with a vitreous luster; beryl has Mohs hardness 7.5–8, hexagonal crystals, poor cleavage, and specific gravity about 2.7. Rose quartz is softer (Mohs 7), typically cloudy, and lacks visible crystal faces.

Formation & geological history

Morganite forms in lithium- and cesium-rich granite pegmatites as a late hydrothermal mineral, generally in Phanerozoic igneous terrains. Rose quartz forms in silica-rich pegmatites and hydrothermal veins.

Uses & applications

Used as a cut gemstone, ornamental sphere, and collector specimen; large polished spheres are decorative. Fine transparent morganite can be valuable in jewelry.

Geological facts

Manganese produces morganite’s pink color, while irradiation or heating may modify its hue. A refractometer, hardness test, and specific-gravity measurement are needed to distinguish it confidently from rose quartz or dyed material.

Field identification & locations

Common sources include Brazil, Madagascar, Afghanistan, Mozambique, and the United States; rose quartz is especially common in Brazil and Madagascar. Look for hexagonal crystal remnants, even color, and no dye concentration in fractures.
