Jewelry from Israel question

[Amanda Lewanski]

Yael, you might be able to help me with something; John's comment on
jewelry on the recreation post reminded me. I have two pieces of jewelry
which say "Made in Israel." One's a ring, one's a pendant. They're
silver, but they have the coolest inset. I don't know if it's a stone or
what. The top layer is clear, and thick, and the layer beneath it is
black, and between the two, so it is set against the black background,
is an image in what looks like stamped gold leaf (or very well-tooled
thin gold). The ring has a rampant lion, the pendant has a flower. The
detail on the gold images is incredible and tiny.

ANYway, my question to you is, since you're there and all that, have you
seen jewelry like this? Can you tell me anything about it? Because the
only material I'm sure of is the silver, I don't know what the black
background is or whether the clear layer is a clear stone or a real hard
polymer or something. Any help would be great; they're really beautiful.
