What is this

Alright 1 in favor of acid bath, it will happen!

I did a quick search and found several similar looking examples called Drusy Quartz. And funnily enough, the examples that looked the most like the pictures above were found in Wisconsin.

I enjoy the geology here a lot

Soaking in CLR and water.

It's doing something! The water turned yellow.

May have to step it up to hydrochloric acid after I wash it a few times. Or just be more patient.

To be honest, “acid bath” just sounded too cool to not do

On today's instillation of what is this

I know it druzy quartz, but it appears to be on some sort of lacey looking quartz. Or possibly lace agate? I am unsureView attachment 130812

Looks to me like drusy (or druzy) quartz on agate and limonite. There does appear to be some lace agate, but that term is often in the mind of the beholder. Last time I checked, lace agate was a lapidary or gem term, and not an official geological term. The CLR ought to dissolve the limonite.

Yes It appears you are correct @Shamar , I really don't know how else to describe it though. Here is an update

I will have to get more CLR tomorrow morning as I do not want to mix hydrochloric acid if there is somehow any residual CLR left in the pourous rock. And I really do not feel like driving 20 miles to get it tonight.

This is off topic but I saw it in a youtube video and for some reason it made me think of you. It's a rare gem found in Australia's Northern Territory - Rainbow Latticed Sunstone.

This is stunning. I haven't bought any gems off the internet yet, this may be the first.

WELL I cannot afford a real piece of that.

I looked it up on the net and looked at lots of pictures, but I never thought of looking for a price. Only found in one small region of the planet suggests that large diamonds would be cheap by comparison.

Time to learn how its formed. Tha k you for sharing this!

Even this example is still amazing

I just started looking at examples for sale, certainly not cheap but not as bad as I first thought. It would be nice to find a piece one day, maybe I should fossick around a bit next time I go back up there.

 

[agateboy]

That would be an awesome experience!

I lived up there for 20 years but never thought of looking for gems. I do want to go back for a visit one day but I need to buy a car first. 32 hours drive from Adelaide to Darwin.
