Need help identifying these two pieces

[twolewts]

Hi, I was wondering if anyone can help me identify these two pieces of jewelry.  One is is tribal looking brooch.  The face feels like a glass material and it has a c hook.  The other is a filigree pendant necklace that has a topaz glass stone with a diamond looking stone.  On the back, it looks like the stone was screwed in. The gold does not stick to a magnet.  What would I list these under as far as catagory and what would be a good start bid?  These two have me stumped.  any information would be appreciated.

Thanks! ;o)

I haven't figured out how to get more than one picture uploaded at a time.  So please bare with me.

your face brooch looks to be by Elzac.  There should be a design patent somewhere. Im pretty sure Ive seen it in a book too.

The second looks to be a revival piece designed after the early 20th century campho glass pieces

Here is a very similar piece on etsy for $220. The pin and face are mounted differently but the pattern is very close.
