Small faceted diamond-like gemstones

Likely diamond (crystalline carbon, C), but visual identification is uncertain

AI-generated identification · may be incorrect

Colorless, transparent to translucent grains with bright adamantine flashes; likely faceted or broken into small stones. Diamond hardness is Mohs 10, cubic crystal structure, no visible cleavage at this scale, and specific gravity about 3.52.

Physical properties

Colorless, transparent to translucent grains with bright adamantine flashes; likely faceted or broken into small stones. Diamond hardness is Mohs 10, cubic crystal structure, no visible cleavage at this scale, and specific gravity about 3.52.

Formation & geological history

Natural diamonds crystallize deep in the mantle under extreme pressure and temperature, commonly forming over roughly 1–3 billion years, then reaching the surface in kimberlite or lamproite. Laboratory-grown diamond is chemically equivalent but manufactured; the image alone cannot distinguish either from cubic zirconia or moissanite.

Uses & applications

Used in jewelry and cutting/abrasive tools. Tiny stones may be melee diamonds or industrial fragments.

Geological facts

The pieces appear geological rather than ordinary glass, but photographs cannot confirm composition, treatment, or natural origin.

Field identification & locations

Confirm with a refractive-index, thermal/electrical conductivity, and loupe examination; moissanite and cubic zirconia are common look-alikes. Common natural sources include Botswana, Russia, Canada, Australia, and southern Africa.
