The difference between tumbled stones and raw stones is based on how they’re treated. The stones are made of the same elements and vary just like anything in nature does, it’s what happens to the stones after they’re gathered from the earth that sets them apart.
Raw stones are what stones look like after they’re pulled from the ground. Nothing has been done to treat them. This is why they often look more like rocks than crystals. They tend to be rougher and lack the shine and sheen of other crystals you’ve seen in stores.
Tumbled stones are, simply put, polished stones. They’re called tumbled stones because they get polished by a machine that tumbles them around until all the rough edges disappear. The process of tumbling the stones is what usually gives crystals that smooth, glossy, shiny appearance.
