Antique 1800 Stamped 18k Turquoise Stone Bird Mosaic Ring- Amazing & Very RARE!!

Description

Gorgeous and very rare antique ring from the late 1800’s. I thought this ring was sterling but this beauty is stamped 18k on the silver colored band and a maker’s mark that I could not make out- both very faint/faded. Not quite sure what the metal content is. The ring was most probably made in Italy- it is handmade and features a square cut robin egg blue turquoise stone with an intricate micro mosaic of a bird. There is a crack in the turquoise due to the age of the ring- but the crack does not go through the mosaic at all. The ring is about a size 5 and weighs about 5.8g. It is a wonderful very rare antique estate piece from a very high end Boston MA estate.
