eruyanik I see you have several rocks listed here (on the forum) and all of them appear to be weathered and well rounded. I know there are reasons to not crack them but on well rounded rocks like these it is frequently difficult to see detail on the rocks due to weathering. A fresh break might make it easier to ID your rocks. However I realize if you are tumbling them this may not be what you want to do.

I can't tell you how many times I've picked up a rock that looks red or some other dark color and after knocking a window in it finding out it's just surface stained.

photograpfic examples are very informative above. by the way thanks to you all for the suggestions. you all are true. i don't want to crack these stones, on the other hand sure i can do if it needs.
additional infos obtained from the stone i have here below:
specific gravity: 3,05
white streak
and i could hardly scratch one or two point with a knife blade (mohs 5-6,5)

That stone look like it may be dense, fibrous, & tough Don’t put much credence in this But it may be in the jade type family Or it may just be basalt But Certainly isn’t a what not... m stly

My first thought, based upon color, was epidote. With the other info, however, I agree nephrite is a possibility. You might want to grind or saw a flat spot prior to tumble-polishing just to give you a base to do an RI if it turns out to be something highly translucent.

However I realize if you are tumbling them this may not be what you want to do. i picked up my rocks from sea shores, so the rocks are in general very well weathered or kind of already tumbled i do not use tumbling, i just have a multidrill set and i use handmade sandpaper discs to polish stones. best regards, Ersin

I am impressed with patience it doesn't take any patience. in the video at 1:11, you can see the sandpaper discs i mentioned. i use this kind of discs with dremel in hand. it doesn't take much time to polish.
