This page gathers the stones in our collection whose accompanying documentation was issued by GIL. Filtering by laboratory is helpful if you prefer to read reports in a format already familiar to you, or if you are assembling a suite and wish the paperwork to be consistent across every stone.
The variety represented here is Mozambique Ruby — corundum whose red colour arises from traces of chromium within the crystal structure. Ruby is judged first on colour: the depth of red, the evenness of its distribution across the face-up view, and whether the tone remains lively rather than darkening in the shadows. Clarity in ruby is read with an understanding that inclusions are natural and common; what matters is whether they interrupt brilliance.
When comparing stones on this page, treat the report as a record rather than a ranking. A laboratory document confirms species and variety, weight and measurements, and, where determinable, comments on treatment — it does not measure beauty. Weigh the written facts alongside the cut, the proportions and the way each stone returns light in the hand.
