Where do the Stones come from? Suiseki Stones are legally collected from a variety of streams and rivers across the world. Different rivers tend to create their own unique stone style due to the ecology of the river and the way in which the water develops the stones over time.
Gemstones are removed from mines in the earth, sometimes in the hard rock where they were formed, but also sometimes in gravels where they concentrated after eroding out of the original host rock. Gems of one form or another occur worldwide wherever favorable geologic conditions lead to their formation.
