Blue gemstone ring, likely lapis lazuli

Lapis lazuli: lazurite-rich metamorphic rock, chiefly (Na,Ca)8(AlSiO4)6(S,SO)2, commonly with calcite and pyrite

AI-generated identification · may be incorrect

Opaque deep blue with carved/polished surfaces and a vitreous-to-waxy luster; Mohs hardness about 5–5.5, granular rather than visibly crystalline, with poor cleavage. The image is insufficient to exclude blue glass, dyed stone, sodalite, or synthetic material.

Physical properties

Formation & geological history

Lapis lazuli forms by contact metamorphism of limestone, typically in Precambrian metamorphic terranes; the finest historic material comes from the Sar-e-Sang deposit in Afghanistan. Comparable deposits occur in Chile, Russia, and Pakistan.

Uses & applications

Used for carved jewelry, beads, ornaments, pigment (ultramarine), and decorative stone; the gold-colored setting appears to be metal rather than geological material.

Geological facts

High-quality lapis is saturated royal blue with minimal white calcite and occasional brassy pyrite flecks. Uniform blue color and curved carving details are not diagnostic of natural lapis.

Field identification & locations

Field identification requires hardness, streak, density, and magnification tests: lapis generally gives a pale-blue streak and shows granular minerals; consult a gemologist before testing a finished ring. Common sources include Afghanistan and Chile.
