I am guessing pic three is moss agate?

Pick four was labeled Lepidote with albite.

That blue reminds me more of copper sulfate than chrysocolla.

Definitely a moss agate in the third shot.

Need a mineralogist - or a more knowledgable hound than me - for that last one.

That is nice lepidolite. Some of it turns brown when left in sunshine for long periods of time.

copper sulfate should dissolve right?
Thanks for the reply’s!!!

Yeah, I've bought copper sulfate in solid form, crushed it and dissolved it to make tree root killer.

Bobbymoon · « **Reply #5 on:** July 24, 2022, 06:37:42 PM »

OK, i have dropped a piece in boiling water and left it for a couple of days, and it doesn't dissolve

Excellent. Is it translucent?

That's an incredibly vivid blue, and the greens nearby indicate the colors are displaying pretty well on my monitor. Nice rock!

That's an amazingly intense blue... so much so that I wonder whether it might be slag. Are there any signs of bubbles? How translucent is it?

I'm thinking gem silica with that intense blue/green...

vitzitziltecpatl · « **Reply #9 on:** July 26, 2022, 07:33:47 AM »

Gem silica is also what I was wondering about when I asked about translucency.

Bobbymoon · « **Reply #10 on:** July 26, 2022, 06:41:13 PM »

The edges are translucent green but the inside is pretty opaque…there’s bands that seem more clear and seem like they would be translucent

That breaks like Turquoise. You may have come up very nicely there! I mean, even moreso than previously surmised!

gunsil · « **Reply #14 on:** July 27, 2022, 08:24:24 AM »

Chrysocolla crumbles like that too. Looks too crumbly to cut an polish without stabilizing so it isn't gem silica but it does look to me like chrysocolla.

Thanks for the heads up!

The fracturing is also suggestive of opal. Owyhee blue opal?

Bobbymoon · « **Reply #17 on:** August 05, 2022, 05:13:26 AM »

Thanks everyone!! I have a hardness tester now so I will check it out with that and post again. Been distracted bought a huge lot of lapidary equipment and stones from a person downsizing so have been busy trying to make everything fit in my garage.

Congrats on the lot you picked up. That's the best way to expand, for sure.

By stabilizing do you mean glue to harder materials then cab? Or is there a treatment you do to the rock itself?
