Carved serpentine wing sculpture

Serpentine-group rock, chiefly antigorite/lizardite: Mg3Si2O5(OH)4

AI-generated identification · may be incorrect

Typically pale green to dark green with mottling, waxy to greasy luster, and fine-grained massive texture; Mohs hardness 2.5–4, with poor cleavage and specific gravity about 2.5–2.6. The feather-like banding is carving and polishing rather than natural crystal structure.

Physical properties

Formation & geological history

Serpentine forms when ultramafic rocks such as peridotite are hydrated during hydrothermal or tectonic alteration, commonly in ancient ophiolites and subduction zones. The sculpted piece is human-processed, so its exact geological age and locality cannot be determined visually.

Uses & applications

Used as ornamental stone, carvings, cabochons, decorative objects, and occasionally architectural material; it is generally less valuable than jade. Avoid acids, heat, and harsh cleaning because polished serpentine can scratch or dull.

Geological facts

Serpentine is a mineral group and rock-forming material, not one single mineral species; some varieties resemble jade but are softer. Fibrous serpentine minerals may include chrysotile, so dusty cutting should be avoided.

Field identification & locations

Identify by its soft, waxy polished surface, green mottling, and ability to scratch more easily than jade; a steel point may mark it, while quartz will not. Common sources include Italy, New Zealand, Canada, the United States, Russia, and China.
