My vibratory tumbler holds up to 3 quarts of rocks, somewhere around 5 to 9 pounds of stone depending on the material, so you can send as few or as many rocks as you like up to about 3 quarts in volume. If you would like your rocks crushed please do so before sending them to me. I will polish them just as received. In the large batch I can polish two or three stones up to about fist sized. For best results there should be a mixture of sizes in the neighborhood of 1 to 2 inches or less in diameter. Tiny rocks may be consumed or crushed during the polishing. I don`t recommend sending rocks smaller than 3/8 inch in diameter unless all the rocks are similarly small.

Pricing depends on the size of the stones sent, please see specifications below: For the Large and Extra Large batch you may send small filler stones of the same type of rock to take up the extra space in the tumbler (less than 3/4 inch in diameter). The smaller stones are likely to be consumed during the process but some of them might turn out nice. Sending small stones is optional.

I have been polishing rocks for as long as I can remember, and polish more than 1000 pounds of semi-precious stones a year... Some types of rocks will not take a high lustre polish in a tumbler. If stones of mixed hardness are sent, then some will come out with a high lustre shine, some with a satin shine, and some with no shine at all. In general, if the rocks have a glassy lustre in the rough state they will take a nice high lustre polish, and if they have an earthy look they rarely take a polish, they just get smooth and rounded. So I can`t make a warranty regarding how they will turn out, though I promise to do the best job polishing that I am capable of given the nature of the stones sent to me, and I will not take shortcuts or wild risks with your stones.

It takes 3 to 8 weeks to complete a batch of rocks depending on the characteristics of the rock and availability of my tumblers.
