Tumbled stones - mix of purchased stuff

I finished up a 6 lb batch the other day, posted the local rocks in separate thread, these pics here are an assortment of purchased materials from various sources. Rocks went through a 5-stage grind cycle, with one week per cycle for everything past coarse grind. Coarse grind varies from a couple of weeks for the dalmation stone, to a month for the amethyst, and even longer for the agate (the agates shown here are the first to squeak through after a month in coarse, there's a bunch more that need longer in coarse).

I was pretty happy with everything except maybe the dalmation, which I would have liked a better shine on. For size reference, a Canadian quarter is identical in size to a US quarter.

First up, dalmation stone.


This is rutilated quartz from a local rock shop.


Tiger eye from the Rockshed.


Tiger eye a bit closer.


Brazilian agate from a local rock shop. Not great banding, but I really like it anyway.


The same agate, backlit to show banding on the thinner stones.


This is one of those mini-geodes you often see for sale in hobby stores or science shops. I just tumbled it until the rind wore off (took over a month in coarse). I had a second one, but wore through to the hollow part.


And lastly is Mr. Big Amethyst, from a local rock shop. I've been trying to do one fairly big rock in a barrel lately. I think the bigger stones are eye-catching enough because of their size to sit out as individual display rocks.


Thanks for looking!
