Bulk Rough Black Obsidian Crystal Large 1" Natural Raw Stones Crystal for Tumbling Cabbing Fountain Rocks Decoration Polishing Wire Wrapping Wicca Reiki Healing Crystals

Great variety of all sizes and minerals. Solid for rock polishing.

Bought a box of rocks.... what more can you say???

Great assortment, large pieces. Will work great in our rock tumbler. Cheaper than science branded tumbling rocks.

I'm fairly new to rock tumbling but I had the lid "pop off" a couple times. I couldn't figure it out till I came across someone who said that my rocks especially the obsidian emit gas when being tumbled. My bag did have 4 about half a palm size pieces of obsidian. Other wise its a good starter bag for the kiddos, just bare in mind.... rocks have gas, maybe someone needs to invent Beano for rocks.

Our great grandson really enjoys the rock tumbling and polishing.

Color is beautiful, clarity is clear, polishing quality was as good, functionality is smooth, very sturdy and ease of use. I would recommend and purchase again.

While the stones are beautiful and I can't wait to tumble them, at least 1/4 (if not 1/3) of the order was quartz. Also, after I rinsed the stones and weighed them I discovered my order was a half pound short. I only had 2.5 lbs in my 3 lb order 😔 For these reasons I can only give a 3 star reviewI will update this review with photos of them tumbled in about 6 weeks or so

This is our second batch of rocks that we will tumble. The first batch came out great, so we stayed with this company. The last time they included a small bag of lucky rocks which were small amethyst. This time it is rose quartz. Nice gesture. A small extra gift to the kids.
