Wedgwood Blue Jasperware Cameo Rectangular Ring Sterling Silver Lady w Snake

Jasper ware sterling silver ring made in England before the 1900's. Estate find. Lady with snake wrap is all I could see when I look at her. No one else taking a shot at that :-) Very old. 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 :-)
