Event

Let’s Find Philosopher's Stone (Dice)!

Most of the stones you can find at our Gemstone House are stones polished stones called “ tumble stones”.
Only, instead of small precious stones, there are some “dices” hidden in the artificial stream. If you are lucky to find one of these dices, you can exchange the dice for rare gemstones like diamond or ruby, or sometimes for large size tumble stone.
There are 8 kinds of dice. According to the picture on the dice, you can get one of the cut gemstones or other large size precious stones!
These dices are always hidden during the opening hours, and some other dices are added during certain events.
You can see the samples of these stones at our Gemstone House Ticket Booth.
