Not even sure I spelled it correctly, but are there any special tips for tumbling it?

I think it is too soft and crumbly - unless you have the gem silica form which is highly agatized...

...and if it is gem silica you would be nuts to tumble it.
I know all the 'tumbled' chrysocolla that they offer in Peru is actually all hand-polished because, as toad said, it can be soft and crumbly at times, so not really ideal for rotary tumbling.

My tip is to tumble it by itself, just long enough in coarse to shape them,not wear them away. It makes a pretty tumble. The harder parts take a good shine while the softer part wont. Here's some I tumbled from desertdweller. snuffy

You might be able to get away with it if you tumble in a 1.5 pounder with a lot of plastic beads. The small size barrel may not be too aggressive. And only with it's own kind. But as the others have stated, chrysocolla is best worked by hand. Look's like Snuffy got some out of the gate, so give it a try. The real nice stuff should not be tumbled. -Chris.
