Blue-green beryl, likely aquamarine in quartz or feldspar matrix

Beryl, Be₃Al₂Si₆O₁₈; the blue-green variety is aquamarine

AI-generated identification · may be incorrect

Translucent pale blue-green area in a rough white host; vitreous luster and hexagonal crystal system if well formed. Beryl is Mohs 7.5–8; the host appears softer and cannot be identified confidently from the image alone.

Physical properties

Formation & geological history

Beryl crystallizes in granitic pegmatites and related hydrothermal veins as magma cools; such deposits range widely in age, commonly Precambrian to younger. The white matrix may be quartz or feldspar.

Uses & applications

Gem-quality aquamarine is cut for jewelry; lower-grade beryl-bearing material is mainly collected as a specimen.

Geological facts

Aquamarine’s color comes chiefly from trace iron in beryl. The pictured piece appears naturally rough rather than cut or polished.

Field identification & locations

Look for a blue-green, glassy crystal with a hexagonal outline and hardness near 8; matrix identification requires closer inspection. Aquamarine occurs in Brazil, Pakistan, Madagascar, Nigeria, and other pegmatite regions.
