Hello :-)
Yesterday I went to the hills to find rocks and came back with big backache and a backpack full of rocks. I got quartz, and some interesting rocks that I’m not sure of what they are yet.
Some of them I believe that I could tumble and others not. I’m trying to use the Mohs hardness scale to classify them. The hardness of most of the rocks is 7 or more because I could not scratch them with a quartz. So far one of the yellow rocks seems to be a 6 because I could not scratch it with an utility knife but could with a piece of quartz.
Here are the pictures of some of the rocks:
The first 3 pictures are from my favorite rock from the group. It is going to go to my aquarium.
I believe it could be petrified wood, but I’m not sure. The size is 2 1/4" L x 2 ½” W. It weights 11 0z and it feels heavy and solid. It is brown/redish with lots of miniature shinny dots that can not be scratched off. It’s hardness is 7 or more. Pet wood???
The next 3 pictures are of a nice looking but strange yellow rock. I don’t know what is is but the lighter mustard color part could be scratched with a quartz and the rest of the rock can’t. This one I don’t think will be a good candidate for tumbling. Here are the pics:
The next rock seems to be a type of geode???. It is about 2 1/4" L x 1 1/2"W and weights 2 oz.
I think that maybe I could tumble this one. Here are the pics:
The next rock I just got it because it resembled a turtle of snake egg. It is 2 1/4" L x 1 1/8" W.
Weights 2 oz. Could it be a petrified egg, a geode? Any ideas on this one. I don’t think this one could tumble well but I just like it! Here are the pics:
The next rock is very beautiful and I think it could be a type of chalcedony, or jasper??? It’s hardness is 7 or more. I really thought it could tumble well and it is already tumbling with the rocks from my first batch that needed another week in 60/90. Here are three pics:
The next pictures are from a group of white rocks. I think most of them are quartz but a couple of the round ones I don’t know. None of them could be scratched with quartz. Here are the pics:
The following brown rocks give me the impression that could hide something beneath that dirt. They could not be scratched with a penny but I did scratch the surface with the utility knife. The first rock is 2 ½” L x 2" W and weighted 2.5 oz. I already put a couple of them in the tumbler to find out more about them. Pics:
In the following picture, the brownish rock at the left had already a silky shine when I saw it, that’s why I pick it up. I don’t know what it is. The beige one is probably quartz.Pics:
The next group of rocks I think are probably some form of chalcedony, or jasper??? The first one, the grey one, I’m not sure. Pics:
Here is a close up of the grey rock. It’s hardness is 7 or more. Color is mostly grey with some black. It’s surface has a natural soft silky shine. It is already in the tumbler. Pic:
Ok, this is my last picture of a yellow rock. Hardness of 6:
Well this is it for now, if you have any idea of what kind of rocks any of these rocks might be, please let me know.
Thanks for looking at my pictures :-)

It's got a lot of beautiful patterns and colors. The reds and the yellows, all I can say is wow. The first piece is also beautiful. Looks like you had a good time ;D
