Question

I have a turquiose ring, round stamped with what I believe to be HH. The first H is very clear although the second letter almost looks like a mistrike H, could be a worn F, E, etc... what do the letters mean??? There are no purity markings that I can see.

Answer 1

The HH is stamped on what? Is the turquoise set in silver to make the ring? Is the HH stamped into the silver?

Or is the turquoise itself carved into a ring (no silver or other metal involved) and the HH carved into the stone?

Answer 2

HH is stamped on the underneath on the inside of the ring on the silver. Stone is set in middle of the setting as a single stone.
