Vintage blue agate ring

This maybe vintage. We know the stone is since it came from nature. Good condition/ used silver wrap ring. Not magnetic. Didn’t acid test this. Blue agate I’m pretty positive it’s blue agate w/ banding.I have not polished or cleaned..It’s quite unique and beautifuI was stuck on what kind of stone it was at first..I know it tested in garnet area but not a gemologist, it is a semi precious stone for certain not glass.. I used the presidium gem tester. .It’s a size 5-8/9 bc the band is adjustable as it’s a wrap ring.not the adjustable type that pinches finger.so I squeezed it too make it fit. It was bigger. Im a 5 so set it there but positive 5-8 I can ck to see if it will go to a 9Not sure if there is a signature. There possibly is but it’s too small to read if so..I give affordable prices as well as discounts on bundles besides what I have now offered. Great prices on natural stones. I was selling on another platform and there I had as of lately 400 listings left. I’m trying to transfer listings by myself ( & add new on here),but I won’t be able to get them all here by listings.Most I deactivated, on top of that I have 1000’s not listed. I have as of lately about 100 pounds added to my inventory as of which honestly I’m trying to just offer live auction or on video.I try to focus on vintage and costume but as you see I usually don’t mess w pure gold. Plated, filled, sterling ect is more affordable.I love natural stones.. If u want customized jewelry box filled. Comment
