I have always been led to believe citrine doesn't occur as a geode which is why it confused me when I read they do occur in this way.

Hi everyone,

I've always been led to believe citrine does not occur naturally as a geode.

I believed all citrine geodes were heated amethyst.

I have just read an article about citrine tha ...

Thanks Philippe, could well be calcite not quartz.

Okay I didn't know that. Thanks Matt.

Looking at some photos of hematite with andradite garnet that does seem like a possibility.

Thanks.

Trying to find out what the minerals attached to this hematite crystal could be? Underneath looks like it may be quartz.

Thanks!

Laurence

Thanks Alfredo, appreciate the info.

Thanks Pete, it's definitely criss-crossed by veins of a dark mineral. Difficult to see any obvious cleavage. When I bought it I was told it was pyrite and the guy I buy from knows his stuff but I c ...

Thanks guys for your replies. Checked it with a magnet and can feel no magnetism at all.

What crystal habit does this piece of pyrite have? Would it be described as massive? Anything else you can tell me about his piece would be greatly appreciated.

Many thanks,

Laurence

This material is sold as prasiolite and I completely understand that's it's absolutely not prasiolite. I'm also aware that some amethyst when heated turns a subtle shade of green and is then sold as ...

Many thanks once again for your help. It's greatly appreciated.

Hey Marco,

Thanks for your detailed reply regarding Kambaba/Kabamba Jasper, it's so much more than I expected and it seems to offer a logical explanation as to why there's so much confusion about ...

It is now Pierre but I looked at it yesterday and it was fine. It doesn't say too much else other than what Pete has already said. I saw this page when I was first researching Kambaba Jasper some y ...

Thanks Pete, I tend to agree with what you've said as well. To be honest, we've been buying minerals in South Africa for some years and I've never found any Kambaba Jasper that comes from there, it a ...

So that German article is what the guy in the other forum that I visited posted.. Here's his translation:

Hey James,

No it's nothing like that at all, it's almost always the same as in the image I posted, colour and markings vary minimally.

Laurence

I thought I'd found the answer that I was looking for but there's so much information on the Mindat thread that it's difficult to work out what stuff is being ridiculed and what's genuine and the most ...

Hi Lluís,

Thanks for your reply, I was actually just reading that thread and commented on the very bottom of it some time ago and those "in the know" do seem to completely disregard any ...

So I've come to my favourite minerals forum once again to pick the brains of the expert members who usually manage to answer my questions!

I've been writing another article for the "Minerals&q ...
