Does tumbling break stones?

Question: Have you ever had any gems break during tumbling? It seems pretty rough to use with gemstone beads, or do you add the smaller ones after tumbling?

Answer: Most stone are fine during tumbling and will take it very well. I find that tumbling softer and porous stones such as turquoise or pearls can make them a little dirty. Even smaller and delicate stones are usually fine during tumbling.
