Here are some pics of rocks that I tumbled over the winter. They are a mix of stuff from the Rock Shed and Lake Michigan finds. Since I ordered a mixed bag, I am not sure of all of the names of the rocks. Some have more factures that I want, but this was my first try with material from outside of MI. Enjoy. Tiger Eye? type of quartz? Moss Agate? quartz amathyst amazonite? turtella sodalite? local slag lake michigan granite agates found in lake michigan crazy lace agates ? ??

Your second and last pictures are citrine. I think I read somewhere that it's not real citrine, but a heated form of some other quartz. It's sold as citrine though. I think that the moss agate is green tree agate. The second to last picture might be carnelian agate. The rocks I like best are the Lake Michigan agates. I'll be on the lookout for some of those!
How did the granite come out? I've been trying to stop picking it up, but it's so darn colorful!

Thanks for the IDs. I've had a lot of luck with Granite. The colors are great. You never get a perfect flawless surface but it will take a shine. I usually put them in with harder rocks as filler. They always come out good. The kids usually divide them up into different sizes and we throw them in depending on the size mix that we want. Keep an eye out for those "Lakers". Do you see any of them in lake Huron?

I do very little rock hunting in Lake Huron because of the algae. I've been going to a private beach that I need my father-in-law to take me to in the spring for the last couple of years. I find Petoskey stones and pudding stones and a few others, but haven't found any agates.
I get granite to polish, but the undercutting bugs me. I'm never satisfied with it, so I try to avoid cluttering up the basement with it. I love the colors though.

The kids take all of the granite anyways. Come to think of it, they take most of what we polish. oh well

Citrine Trivia - jugglerguy nailed it when he said Citrine is sometimes heat treated quartz. Brazilian Citrine is often actually heat treated Amethyst. If you look closely under a 10X hand lens, you will actually sometimes see little flecks of purple that have not been completely converted by the heat treating. Heat treated Amethyst to Citrine tends to take on a darker caramel golden-brown colour. Natural Citrine can occur in nature, is much rarer, and tends to be a lighter golden-yellow colour.
Share the above information at your next social gathering and you'll understand why rock hounding can be lonely sometimes.
Keep searching for those local Lake agates. They're prized.
Darryl.

Yes Rob, I think it is carnelian too. Again, may be a heat treated speciment which is very common with carnelian.

Nice variety there... I like the local stuff the best and the sodalite is eye catching as well. I've ordered several bags of Rocksheds mixed rough and always enjoy sorting and tumbling it.
I'm another granite-a-holic....say I'm not picking it up but always bring some home.

I'll echo what others have guessed for those 'purty reds as Carnelian, and take a stab at those greens and say they might be Aventurine or Fuschite. Nice variety!
