$300 for 1.5 hours and includes 50 bags. Each additional bag is $5. Each child gets a keepsake bag to take their gems in and also has a chance to identify their gems on site. Specific gems are not guaranteed. We need to have a water and electric source for set up. Gem mining is a fun experience to see the beauty and history of the treasure hunt :0 ) It is a great learning experience and you can use your gems to decoreate a flower pot or Gnome / Fairy Garden.
