Octopi - Sterling silver ring

So I was watching a show about this guy who befriended an octopus.  I guess it stuck in my head.   This was inspired by the show but it's not meant to be an exact representation of an octopus arm(?) limb(?).

Solid sterling silver round (not perfectly), overlapped and lined with little bumps all along the top ridge.  The band isn't a perfect circle either.  Then oxidised to a lovely mottled grey with silver showing through.  This will change over time with wear (rub off some of the oxidation) then the atmosphere will cause more oxidation (never ending cycle).  

Inside has a comfy soft curve.  Size is NZ T 1/2 (ish) not a perfect circle, as I said.
