Ave!
Ring, Medieval, Childs, with Mystic intaglio
Copper alloy; 3.2gm, Ring size 4; wearable ca. 16th-18th Cent AD
The subject of the intaglio is moot; it could be a simple design or represent mountains? This lovely ring was certainly worn by a child or young lady...and hopefully be worn by your lady.
Such rings can only be improved with wear, as the natural salts and oils will bring it back to lasting beauty. Wear this ring!
