F.M.B, a now-defunct domestic brand, Full Metal Box stone ring. The stone is labradorite. It's more beautiful than it looks in the photos! The lines you see in the stone are natural cracks unique to natural stones, not breaks. Size is 19. Authentic silver 925. Ring only will be shipped. There is some wear and tear, but it's in good condition. Please refrain from purchasing if you are sensitive to used items.
