Polish YOUR rocks

Do you have some amazing rocks, but not a way to polish them? Let me take care of it. I’ll polish 1-3 pounds of rocks for you. Just ship them to me and 30-45 days later, I will send them back. That’s how long it takes to go through the tumbler. More than 3 pounds, just add $25 for each three pound group. 
Rocks the size of a quarter or a smidge bigger are the largest that can tumble. Sandstone, sifter composition, or those with a lot of crystals do not work in the tumbler.
