Wedgwood Blue Jasperware Cameo Rectangular Ring Sterling Silver Lady w Snake

Jasper ware sterling silver ring made in England, early1900's. Estate find. Cobalt blue jasper ware with ghost white female with a snake wrap? is all I could see when I look at her. Anyone else taking a shot at that? :-) Very old. Hexagon/rectangular shape. This one won't get caught in your jeans' pocket. Win. Most of the ones out there are oval or marquis shaped. Size 6/3/4 to just under 7. Tested as sterling. Signed. In fine condition. I have polished lightly with silver cream and cleaned the cameo with hot soapy water and s toothbrush. Measures 7/8" long and about 5/8" across. Could not polish the inside. All my items for sale come from a non smoking home. PLEASE enlarge all photos as they're a silent intergral part of my items' description. Thanks for looking :-)
