This is a very niche ring. It's solid 925 silver but the silversmith has created a rough, steel like texture which gives it a rugged, almost masculine character. The individual sections of the shank are separated by gold plated lines. The central opal (untreated) is Africa and has a good fire. Size is UK 'Q', USA size is '8'. Very comfortable to wear. Hallmarked as solid Sterling Silver 925 at the Edinburgh Assay Office. Gross weight 5.9 grams.
