My first mabe pearl

[hungry4nacre]

I recently acquired this mabe pearl pendant from an auction. I paid $34.77 after closing costs. Seems like a cream body with some rose overtone. It's also decorated with what looks to be a peridot and either a ruby or garnet. There are no hallmarks on the pendant but I am going to assume it is sterling silver as it also came on a sterling chain (not pictured). There is a chip at the top near the bell but considering this piece is probably older than I am it looks wonderful for its age.

Maybe I got ripped off or maybe I got a great bargain. Either way I absolutely love it!

Somehow it doesn't strike me as a Mabe pearl...looks like a freshwater pearl to me. The flattened back is the setting itself.
It could be a natural blister pearl...I would need to see more details (side photo), but it just doesn't look like a Mabe to me.
But it sure is a very special piece...very interesting!
