Rock Tumbler Grit Set, Rock Tumbler Grit Polish Refill - 4 Basic Step Tumbling Media (Coarse/Medium Grit/Pre-Polished/Final Polish), Rock Tumbler Set 2.0 for Any Brand of Rock Polisher

Great for the price

Followed all the steps in the right order. Ran the tumbler for over a month through all the steps. In the end, all of my stones are now a dull matte finish and not even as shiny as they were before they went through the processes. I don't blame this product completely- all of these kits seem about the same as far as materials go- I just think the whole process is a waste of money, time, electricity, and misrepresented as 'stone polishing'. Completely ruined my emerald, rubies, sapphires, opals, and tourmaline as well. I will have to hand polish the ones that are still large enough to secure, or coat them with something to get a shine out of them now. And some of them just ended up too small or even sand like.

Works great but had to purchase tumbling sponges separately to get the slick shine or clear finish on the quartz. Directions are simple and easy though.

Works well as expected

Great gift for my niece. She loves rocks and I bought her a rock tumbler. It was a good value . Great for a 6-13 yr old

My son has been into collecting gem stones. He got some gem stones that he could polish and someone gave him the machine. So my husband and I decided to suprise our son with this product. He had fun experimenting with this and gem stones came out polished beautifully. I didn't know such things exsited lol but Amazon has everything!

Price was right - I tumble rocks and glass

I was missing grit 1
