Georgian Carved Fede RingFede rings are traditionally betrothal rings with the design of clasped hands dating to the Romans. The central hard stone cameo set in what we call a collectors mount, features clasped hands in agate with two turquoise colored stones set on either end. One stone is Odontolite while the second stone is Persian turquoise. Odontolite is a very rare stone. Odontolite is a fossil that has naturally been colored in the earth to a turquoise color. English
