Materials: Brazilian imperial topaz (tested), solid 18k yellow gold (unmarked; tested with electronic gold tester & nitric-muriatic acid)
Weight: 6 grams
Workmanship origin: British
Height of pendant: 46.8 mm (including bail), 40.5 mm (excluding bail)
Width of pendant: 32 mm
Dimension of topazes: 5 total— three 9.25 x 5 mm, one 14.6 x 5 mm, one 5.75 x 6 mm
Approx. weight of topazes: 7.78 ctw (three 1.46 ct, one 2.31 ct, one 1.09 ct)
Condition: a 1.2 x 1.6 mm shallow conchoidal chip to the lower left of the bottom topaz (not noticeable to the naked eye), another tiny 1x 1 shallow conchoidal chip to upper left of top topaz (very shallow, along facet plane, difficult to spot even with loupe). Under loupe magnification, I can spot some tiny age-related nibbles and abrasion along facet junctions. Tip of pendant has a piece of later reinforcement / brace (not break evident, added for strength and to prevent a break), along with some faint touches of old solder in that area. There’s an original production seam to the bail. Age-related surface wear and patina to the gold throughout.
