The Ocean Rocks are now complete ... I would have to say they turned out quite nice! I did 2 seperate batches one with 50% more smaller stones in the 1/4 inch range... about 1/3rd of total load.... than the other batch. As it turned out the batch with the smaller stones polished brighter and more uniform!!!!!! For new tumblers the steps I took for tumbling the beach rock are posted in the worlds largest rock tumbler.........I would think these steps will work for smoothed river rock as well....... ANYONE OUT THERE know of some good books on identification of material I have divided my stones into groups based on color I know the agates and quartz but have know idea what the reddish brown-reddish orange are as well as the green-marbled green and solid black ones are HELP?  ?

Hurk,
Do you have a digital camera? If so, post a few pics across and I will identify the stones for you.
It's not really possible to identify a type of rock by color alone, and you may find that they are a conglomerate of some sort.
I would be interested to see what you have turned out.
Cheers
Andrew

Hi Hurk,
I am also new to rockhounding and tumbling. The two most useful books I've found so far are the "National Audibon Society Field Guide to Rocks and Minerals - North America" (it's pictures are arranged by color of rock) and the Handbook of Minerals and Gemstones" by Walter Schumann. Both should be available at any large bookstore and are definitely available online.
Where did you collect your ocean rocks? Much of the red/orange/brown opaque rock along the California coast is Jasper, which is in the quartz family.

Hi, I agree that the reddish brown ones could be Jasper, they could also be Carnelian or Brazilian agate, the Green marbled ones could be green moss (or green tree) agate and the black ones could be Onyx, Obsidan or black chalcedony. Can you see through the black ones if you hold them upto the light?? if so, they could well be apache tear.
BUt I agree that you should definately try and post some pics of them.
;D
