What we do

Reports you can rely on before you buy or sell

The market now includes synthetics, composites and treated stones. A laboratory report tells you what a stone really is.

Gemstone identification

Confirms whether a stone is natural, synthetic, composite or an imitation, and names the gem species.

Treatment identification

Detects treatments such as dyeing and glass filling so the report discloses what has been done to the stone.

Diamond grading

Color, clarity, cut and fluorescence for single diamonds and for jewellery set with one or many diamonds.

Colour stone grading

Ruby, blue sapphire, yellow sapphire, pearl and emerald, with treatments noted where they apply.

Why a lab report matters

Rarity, originality and durability decide the value of a natural gemstone. Treatments and synthetics can look identical to the eye, and only instruments can tell them apart.

  • Treatments disclosed where applicable
