Pink tourmaline crystal (likely polished or rough-cut)

Elbaite, Na(Li₁.₅Al₁.₅)Al₆(Si₆O₁₈)(BO₃)₃(OH)₃

AI-generated identification · may be incorrect

Pink, translucent crystal with a vitreous luster and visible internal features; tourmaline is trigonal, typically Mohs 7–7.5, with poor cleavage. The image alone cannot confirm the identification or distinguish natural color from treatment.

Physical properties

Pink, translucent crystal with a vitreous luster and visible internal features; tourmaline is trigonal, typically Mohs 7–7.5, with poor cleavage. The image alone cannot confirm the identification or distinguish natural color from treatment.

Formation & geological history

Elbaite crystallizes in boron-rich granitic pegmatites and hydrothermal veins as magma cools; specimens may form over geologic timescales, commonly in Precambrian or younger pegmatites.

Uses & applications

Used as a gemstone in jewelry and as a collectible mineral specimen; industrial use is limited.

Geological facts

Tourmaline crystals can be strongly pleochroic and often show color zoning along their length.

Field identification & locations

Pink color and crystal-like shape suggest tourmaline, but the image lacks diagnostic detail; check for a prismatic, striated crystal habit and verify gem identity with testing. Common sources include Brazil, Afghanistan, Mozambique, and California.
