Silver ring from earring

What to do with the earring you haven’t lost?

Sometimes I can make a near copy, but in this case the mosaic pattern was not reproducible.  In the past I have converted the earring to a pendant, but, for this,  I was asked to make a ring of it instead.

The earring is glued to a square base plate that fits the inside the back of the earring once the stud is removed.
