A beautiful ring with crisp hand engraved flowers along the shank. "MIZPAH" Front and center, with full British Hallmarks along the interior along with a mysterious engraving that is very hard to read.

Leopard’s head is the London assay office, meaning  the ring was tested and certified in London. 625 is the mark for 15k. O for the year it was produced, likely in the 1930s. Size 8, 3.8g, 7.27mm in front, tapering to 1.72mm around the back.
