Vintage Chrysocolla Israel sterling 925 signed WA 6 in shield cuff outlet bracelet Gorgeous

These stones are awesome. I believe the stones are Chrysocolla which comes outlet from Israel. This is signed with lots of detail. It stamped Israel 925 also looks like a WA in block and a letter B on top of maybe an A. I have had this cuff for many many years. And it's a 7 1/2 inch. It has a lot of tarnish which I never polish I let you decide. I love original patina.
