You don't have to be a meteorologist to know the Nimbus.  A Men's Black Tungsten ring with a satin black brush finish.  The polished round edges along side the brush finish gives the ring definition. An 8mm band width to produce a nice bold appearance.  The only thing it can't produce is lightning... sorry about that.

Comes 8mm unless requested otherwise. 4-10mm available, also custom 1/4 sizes.
