18ct Yellow Gold Black Onyx Oval Stone Set Signet Ring
★★★★★ Read all reviews ?
The contrast between the black opaque onyx and the rich buttery 18ct yellow gold in this oval signet ring creates a bold, refined look. Onyx is a polycrystalline quartz that has been used in fine jewellery for centuries. Hancocks have been creating hand engraved signet rings since 1849 and since then have always maintained the highest level of craftmanship.
