20s or 30s Paste Necklace

I just won this on ebay for $46 which I think is a good price. It's a sterling paste necklaces from the 20s or 30s.  And nearly 18" in length, which is a good size for me. I'll probably end up using it with 18th century or regency stuff since it's collet-y.

Isn't it pretty? It's from one of my new fav vintage/antique jewelry sellers, nalfie.  They have really nice stuff. (Thanks Taylor!)  I nicked their ebay pics since I don't have it yet.
