The gem-washing process starts by selecting one of the sandbags. There are 4 different sandbags to choose from: 

  • gemstone-sand
  • tumblestone-sand
  • gold-sand
  • diamond-sand

The gemstone-sand conains rough natural gemstones and minerals. 

The tumblestone-sand contains smooth polished gemstones. 


The gold-sand contains fool's gold nuggets.


The diamond-sand contains polished glass diamonds.

Every sandbag comes with a postcard that helps identify the stones and contains additional information, as well as a small bag with your logo to collect the stones.

Your guests pour some of the sand into the washing-strainer. Then they hold it in one of the washing-flumes. Soon they can watch how the hidden gems, tumbled stones, fool's gold nuggets or glass diamonds appear.

The older gemstone-hunters may use the washing-pans to find gems. They start by pouring some sand and water in the washing-pan. By moving the washing-pan circlewise the sand will be washed out at the edge and the treasures gather at the bottom.

With our postcards your guests can identify the gemstones, collect them and trade them with other gem-hunters.
