As you can see in the pictures there is a lot of tarnish on the front and back. Unfortunately, I don't know much of anything about it. I looked up the mark on the back and from what I found it was made by Alvin Sosolda but I can't confirm that. It will come carefully wrapped in a plain white gift box. Pictures have been enlarged to show details and or any flaws.
Some pictures were taken with the flash on. Please enlarge and take a good look at all 21 pictures.
They are a major part of the description. Also, please refer to them for weight and measurements. If you have any questions please don't hesitate to contact me. I also have sterling jewelry listed along with many pieces of vintage designer signed and unsigned costume, fine and artisan jewelry if you'd like to take a look.
