Vintage Sterling Mesh Choker / w 18k Trim

This is an intricate sterling silver mesh choker with 18k gold trim.   It has a fluer de lis as a closer.  The pendant can be seperated from the necklace and has a dark stone.  This is very old and well made and is a hefty 47.9 grams.  It is signed on both ends of the choker sterling and a signature that I can't decipher.  On one end I can see sterling + 18k.  This is in very good condition, I have never looked at a piece of jewelry as much as I had to look at this one.  It is very interesting & I hope the pictures can show the details.
