Sterling silver 925 over bronze Kombaba Jasper size 7

Beautiful sterling silver ring that is sterling silver over bronze. This is not a solid sterling silver piece and has been tested. Never been worn just tested. On the back of the band, you will see a small section from the scraping of it being tested, revealing a little bit of bronze. I am selling this as a costume jewelry piece even though the stone is genuine. This is Kombaba Jasper, and it is very unique.
