Vintage Goldtone Swirl Pin Diamond Cut Design and similar items

This week we are listing jewelry from two different estate sales in West Texas. The pieces are from, I believe, the 30's to the 60's and there are some designer names. There are a lot of quality pieces even though most are not marked. For sale this week is this textured goldtone pin, I think this is probably a newer pin from the way the rivets look on the back. It measures 2 1/8" tall and 1 7/8" across at the widest point. Jewelry is like art, unique designs, different colors and shapes of stones. Each piece tells its own story, some of which are crafted by famous designers. You can collect what you like according to your taste and in any price range you choose. As most of my items come from estate sales they are in used condition and will be sold as is. I try my best to check everything out and clean it if I can. I don't sale damaged items, without pointed to the flaws, but I am only human so please ask questions before bidding. Thanks!
