Detailing the unique characteristics of coloured gemstones with advanced instrumentation and expert analysis — from species and variety to colour, for complete confidence.
JTR Gemstone Identification Reports provide comprehensive identification of coloured gemstones, detailing the unique characteristics of each stone.
From species and variety to natural or synthetic origin and treatments, our advanced instrumentation and expert analysis document what defines a gemstone’s identity and value — so buyers and sellers can trade with certainty.
The Gemstone Identification Report pairs comprehensive identification of coloured gemstones with an interactive JTR360 view — a 360° video of the actual stone that can be rotated and examined from every angle.
It is the first coloured-gemstone report in the industry to include a visualization of the actual graded stone, giving traders and consumers unmatched transparency and confidence in what they are buying.
Identifies the gemstone species and variety — such as corundum resolving to ruby or sapphire — using advanced spectroscopy and gemmological analysis.
Confirms whether the gemstone is natural or synthetic and detects treatments that affect its identity and value.
Documentation of hue, tone and saturation — the most important value factor for coloured gemstones — assessed under controlled lighting.
Precise weight on validated micro-balances, together with millimetre measurements of the stone.
Assessment of shape, cut style and proportions, documenting how the gemstone has been fashioned.
An interactive, frame-by-frame 360° video of the gemstone that allows examination from every angle. An industry-first feature for unmatched transparency.
