Semi-precious gemstones are found all around the world in a variety of colours. Diamonds, rubies, sapphires, emeralds, turquoise and onyx are several examples of semi-precious stones. While quite hard and durable, semi-precious stones still require special care and cleaning techniques to bring out their lustre and prevent scratches or dullness. Always store your gemstones separately in a soft bag or fabric-lined jewellery box.

Skill level:


  1. 1

    Fill a bowl or container with warm water and 2 or 3 drops of dish detergent.

  2. 2

    Dip a soft cloth into the soapy water and wring it out or dip a brush into the water and scrub the gemstone thoroughly to remove any residue, dust or dirt. For pearls or other soft stones, only use a soft cloth to wipe away dirt.

  3. 3

    Rinse the gemstones thoroughly under lukewarm running water. Use a stopper in the sink to prevent the gemstones from going down the drain if you drop them.

  4. 4

    Wipe the gemstones with a soft cloth to dry them and bring out their shine.

Tips and warnings
