Condition: under loupe magnification, I can spot age-related abrasions to the gem facet junctions (difficult to spot with the naked eye), 3 of the 28 halo stones have a small nibble to the girdle/edge, and 1 has a small pin-sized cavity/chip (not visible to the naked eye). Overall, the gems are in good condition for the age, and lack major eye-visible flaws (please view videos and photos). There’s a production seam where the center trifucated fleur-de-lys ornament joins the shoulder; this is original and present in many late 18th c Portuguese rings. Some age-related patina, tarnish, and light surface wear to the gold and silver.
