Vintage silver ring with blue stone

Vintage silver ring blue stone. From my family's estate. It's quite old though I'm not sure what the blue stone is. Light shines through it handsomely. Somewhat darker when worn. Signed. Very smooth and comfortable to wear. Had a very interesting medieval look with the silver turrets (platform) around the stone. I am not sure of the brand. It could be a James Avery or similar Vintage brand. It's also possible this is white gold and not silver but I can't tell from the signed markings. Please ask any questions and look at my pictures as I do not accept returns. All of my items are well cared for and come from a smoke free pet free home. Men's or Women's/ Unisex I measure it as approx a size 10-11 Gift boxed #Father'sDay#gifting#Vintage#ring
