Dates to the Victorian era or earlier.
Crafted in solid 22 carat yellow gold. Bears a curious set of hallmarks that I am having difficulty with: a right facing lion passant (usually used by Gotham), the maker's marks of 'G.S.' and the hallmark '22'. There appears to be a mis-stamped hallmark as well, just before the lion passant.
The rounded edge band measures approximately 2.35 mm (0.09") from top to bottom, with an average thickness of 1 mm (0.04") from front to back. The ring weighs 1.6 grams and is currently a size 4.5
Condition is very good, with no damages or repairs.
