Additional information


We use a new generation of concrete for our jewelry called ultra high performance concrete which has the compressive strength of 150 Mpa. Over 20 times stronger than traditional concrete. We offer a lifetime warranty on these rings, if the concrete were to chip or break at anytime, we will replace it.

Sizing Information

If you are unsure of your size, please visit a local jeweler to have your finger sized accurately. Be sure they use a wider sizer, close to the size of the ring as wider rings will fit tighter. Do not use sizing charts as they are always inaccurate.
