Fossilized Opalized Wood Ring Size 9.5

When wood petrifies it turns into a type of stone - in this case a form of opal. Though not the shiny type with colour-play you're used to seeing, these particular stones often have a beachy feel, reminiscent of a tropical shoreline. 

Size 9.5, though with a wide band it may be better suited to a size 9. I'd recommend trying this one on in-person.
