The M81 ring covers both sides of the hand. – just like a glove.
The ring is set with a bunch of light-pink, bright-pink and hot-pink rubies on one side and white zirconia stones on the other. The stones roll around and rotate freely inside their settings and form a kind of a symphony when worn on a hand.
The M81 weighs about half a kilogram and is certainly not the most practical ring but it is an unique piece of an art object that could never not have fun.
