Natural oils on your skin will darken the concrete slightly during wear.
The concrete has been sealed with a non-toxic sealant.
Due to the nature of concrete, no two pieces are exactly alike. Each piece has slight variances (i.e., bubbles and colour) that add to its charm and character.
Avoid dropping your jewellery or hitting hard on surfaces.
Remove jewellery prior to bath, shower and swimming. Prolonged contact with water might soften concrete despite the protective sealing.
