Gemmologist's Equipment - The Refractometer

A refractometer measures a gemstone’s refractive index — a key optical property that helps identify stone type.

By placing a drop of contact fluid and touching the gem’s surface, the instrument reveals how light bends inside the material.

Results distinguish between similar-looking gems, detect double refraction, and can flag synthetics or imitations.

Fast, non-destructive, and reliable, refractometers are essential tools for accurate gemstone identification in the lab or field.

Consult Megan Austin Valuations today for your gemmological needs.

This antique 9ct gold and silver Masonic ball pendant came across my desk for valuation, and what a beauty !

Sought-after by collectors, Masonic ball pendants (or orbs) blend history and symbolism. Usually crafted in gold or silver, they feature fine engraving and sometimes gemstones. The sphere opens to reveal a cross-shaped emblem with Masonic motifs — discreet symbols of membership and moral values. The globe hints at the universe, and the cross the four cardinal points.

Behind every gemstone discovery is the precision of gemmological equipment.

From refractometers and spectroscopes to microscopes, polariscopes, and UV lamps, these tools reveal what the naked eye cannot: spectra, structure, fluorescence, inclusions, and optical properties.

Each instrument helps gemmologists identify stones, assess quality, and uncover their unique stories.

Contact us today to make an appointment with our Qualified Gemmologist, a member of both the Gemmological Association of Australia (FGAA) and the Gemmological Association of Great Britain (FGA).

Fluorescence is an important clue in gemmology, revealing how some gemstones respond to ultraviolet light. It can help identify natural materials, detect treatments, distinguish similar-looking gems, and support provenance research.

While fluorescence alone doesn’t determine value or authenticity, it adds valuable evidence when combined with careful observation and other testing methods. This fascinating phenomenon connects science with the hidden beauty of gemstones, making every examination both informative and intriguing too.

Check out this reel that separates Kunzite from Morganite using fluorescence.
