Vintage Antique Silver Signet Coat of Arms Crest Blue Enamel Ring

A Vintage Antique Silver Signet Coat of Arms Crest Blue Enamel Ring. A very cool ring with a decorative face that appears to be a family crest or Coat of Arms. The ring weighs in at 14.8 grams on my scale and has a face that measures 23.5mm tall x 23.5mm wide. The ring is approximately size 10.5 on my ring sizer. We are not sure of the purity/ quality of the silver. I believe someone added the enamel after the ring was made.
