Wash your gemstones in mild soap and rinse well with water. Dry thoroughly and polish with a cloth. Avoid contact with perfume, hairspray, and the like, as some stones have a porous surface and can be affected by exposure.
Gemstones are genuine natural materials and absolutely unique. They vary in color and have unique inclusions and features that show their great age and natural beauty.
Note: Some stones are naturally softer and will have a less sharp facetted look after long use.
