Condition Notes: This sapphire exhibits a distinctive steel-blue coloration with great clarity and measures 12.40 x 9.26 x 4.82 mm. GRS has identified this sapphire as basaltic in origin, meaning that determining a definitive geographic origin for this stone is not possible, as diagnostic indicators remain inconclusive among basaltic sources. Minor abrasions and nicks are visible under magnification along a few facet junctions but are not eye-visible. One diamond accent shows a small nick, and another, held in shared prongs, is slightly loose in its setting.
