Physical properties

Transparent, vivid red, vitreous luster, faceted cut; natural ruby hardness 9 Mohs, while glass is about 5–5.5. The blurred image shows no diagnostic inclusions or crystal features.

Formation & geological history

Natural ruby forms in metamorphic rocks and some igneous environments over geologic time; synthetic ruby is laboratory-grown, and red glass is entirely manufactured.

Uses & applications

Ruby is used in jewelry, watches, lasers, and abrasives; synthetic ruby is common in jewelry and industry. Red glass has mainly decorative value.

Geological facts

A ruby must be corundum with a red color; other red gemstones such as garnet, spinel, and tourmaline are not ruby. Faceting alone cannot establish identity.

Field identification & locations

Confirm with hardness testing, refractive index, specific gravity, and magnification; professional gem testing is safest because damage is possible. Common natural sources include Myanmar, Mozambique, Sri Lanka, Thailand, and Madagascar.
