Antique Sterling Silver Large Hollow Carved Acanthus Ring

Unstamped, tested sterling silver. Victorian circa 1900s, Hand carved hollow acanthus motif. Large flat top with signet similarities. The interior is completely oxidized. I have left the natural patina to the interior to help with the preservation of it’s true age. There may very well sterling and/or maker’s hallmarks on the interior. Can be cleaned if desired. Absolutely enchanting. Solid sterling and can be sized.
