This beautiful 375 9ct gold ring has numerous pave set diamonds to the shanks and surround with a central black looking stone that tests as sapphire but when a light is passed through it, it is a very dark blue. The diamonds really catch the light. All stones have been tested with a presu]indium gem stone tester. It carries a full hallmark and is in very good vintage condition. No stones missing and no damage. It has a full set of hallmarks and is a good sized ring. Happy to answer any questions or supply more photos. Thanks for looking.
