This is an antique art deco period 18ct gold, platinum and 0.25ct diamond solitaire ring in a size J, US 4 3/4. The head measures approximately 6mm in diameter and the band is around 2mm in width and 1mm in depth so is nice and solid. The diamond is set into platinum and measure aproximately 4mm with a total carat weight of approximately 0.25cts. (I do not know the cut, colour or clarity as I am not a jeweller so apologies for this, but the stone is nice and bright.) It is in very good condition for its age and it weighs approximately 2.8g. It is stamped with '18ct PLAT' as pictured.
