All natural stone is porous and can absorb moisture from the environment and skin. Over time, you may notice dry or matte areas, especially if a piece is stored away or worn infrequently.
Regular wear helps maintain a soft, even sheen. To refresh a piece, you can gently rub it against your skin for a moment.
For deeper conditioning, apply a small amount of a neutral, odourless oil such as castor oil. Rub lightly into the stone using your fingertips, allow it to absorb for a few minutes, then remove any excess with a soft cloth. This will restore depth and surface richness without changing the natural feel of the stone.
Over time, each piece develops a subtle patina through use.
