Colorless faceted gemstone, likely a small diamond or imitation

Undetermined; diamond is carbon (C), but visual appearance alone cannot distinguish it from cubic zirconia or glass

AI-generated identification · may be incorrect

Small, colorless, brilliant-cut stone with strong-looking sparkle. Hardness, crystal structure, and specific gravity cannot be established from the image; diamond is Mohs 10, cubic zirconia about 8–8.5.

Physical properties

Small, colorless, brilliant-cut stone with strong-looking sparkle. Hardness, crystal structure, and specific gravity cannot be established from the image; diamond is Mohs 10, cubic zirconia about 8–8.5.

Formation & geological history

If diamond, it formed deep in Earth’s mantle under high pressure and temperature, commonly billions of years ago, then reached the surface in kimberlite or lamproite. The stone’s identity and origin are not verifiable from the photo.

Uses & applications

Faceted stones are used in jewelry; diamond also has industrial cutting and abrasive uses.

Geological facts

Faceted appearance is not proof of diamond: cubic zirconia and other simulants can look similar. Identification requires gemological tests or a reputable grading report.

Field identification & locations

A loupe may reveal facet wear or inclusions, but reliable identification uses thermal/electrical testing and refractive measurements. Common diamond sources include Botswana, Russia, Canada, and South Africa.
