Gold
Overall Condition: Very Good
Condition Notes: This prominent sapphire and diamond ring centers a velvety rectangular sapphire measuring approximately 9.72 x 8.90 x 5.53 mm. The sapphire exhibits a rich saturation and soft internal glow, with minor abrasions visible along the table facet junctions under magnification, consistent with wear. Flanking the center stone are emerald-cut diamond accents, each measuring approximately 5.50 x 3.50 mm and displaying VS clarity, offering crisp contrast. A facsimile copy of the GIA Sapphire Origin Report will accompany the sapphire.
The ring is crafted in platinum, with XRF testing indicating notable palladium content in certain areas. The diamond settings appear to be executed in a gold alloy. The shank shows moderate to heavy wear, particularly at the base, though it remains structurally sound.
