Ring size: USA 8.75, UK Q ½, EU 58.5 (not resizable)
Materials: vitreous enamel, solid 18k yellow gold (unmarked; tested with electronic gold tester & nitric-muriatic acid)
Workmanship origin: English (provenance: from a Westphalia, Germany private collection of early rings)
Weight: 6.6 grams
Inscription: [M. R. obijt 16 Maij 1683] (to interior)
Width of band: 4.9 – 5.1 mm
Thickness of band: 1.9 mm
Condition: age-related surface wear to gold and enamel (losses, worn down in areas). Some partial restoration to the enamel, done properly with fused powdered glass (same material as original; indistinguishable in appearance and quality from original) fired at 1400-1500ºF. I have tested the enameled areas throughout with a steel blade; this ring is 100% hard vitreous enamel, without later epoxy or acrylic material. Inscription to interior is still clear; hoop still in a nice circular shape.
