108 Admirers

A good 18ct gold Art Deco ring that was made circa 1920-1930. It is set with a blue sapphire that sometimes takes on a greenish colour in certain light. It is surrounded by small white well matched diamonds. The top is platinum with millgrain work around the sapphire. This was done by using a knurling tool to achieve the bead effect. It would be a pretty engagement ring.
