Understanding the dossier fields
Length-to-width describes the outline. Table and depth are proportions, not quality scores. Fluorescence describes a response under ultraviolet light. Cut interpretation describes the historic or stylistic character seen by the dealer and should be considered beside the laboratory report and videos.
Dealer description and photography by Mr. Mortdechay Mordechayev, G.G., diamond cutter and antique-jewelry specialist.
This 3.09 ct F, SI2 Old Mine Cushion Brilliant has the generous outline and broad, unhurried facet pattern sought in a fine antique cushion. Its shape, depth and hand-cut facet layout determine how it returns light.
Its F colour is best considered together with the cut: in an individual stone, tone and facet character can be far more persuasive than the letter alone. The SI2 clarity grade should be judged face-up and in motion; our close views show the stone as it is seen, rather than reducing it to a line on a report.
The stone is accompanied by its GIA report. Review the reports beside the on-hand and 360° videos, then arrange a private viewing to assess brightness, fire, contrast and face-up character.
