GEMSTONE EXAMINATION

A closer look at your gemstone

Three methods used in gemstone identification.

Refractive index →

A refractometer measures a gemstone’s optical properties. Refractive-index readings provide clues to its identity when considered with other examination results.

Specific gravity →

Specific-gravity measurement compares a gemstone’s density with water. The result helps distinguish materials with a similar appearance.

Microscopic examination →

Magnification reveals inclusions, surface features and internal characteristics. These observations help assess gemstone identity and possible treatment indicators.
