Don't know if this should go here, but here it is. A while back, I posted a pink lepidolite with ruby. Well, this morning, I was going through some cabs and noticed that the stone had turned partially green!! Never saw that before! WTH?? The first thing that I thought was that I must have put it in its baggie before it was completely dry and it had molded. Seeing how there are thin mica layers in this maybe water got under the layers? Dunno. Weird.

Interesting!!! Hope somebody has an explanation. Something to watch for.

Could it be some sort of oxidation? Was the rough rock pink?

Was it sitting in the sun for any amount of time? UV rays can change the color of a stone... I've seen Blue Lace agate turn grey in a matter of weeks.

life ... but seriously: is mould possible? I really wonder. I will dip it in bleach later and find out. If it is, it's not just on the surface.

Is it possible there was a chemical reaction with/from your water? This is quite interesting. Hope you figure it out!

Well, nothing else ever has had a reaction, including other lepidolite and this didn't show up until long after it was cabbed. Lepidolite is lithium, which, I believe, is a salt. There is ruby, too. It is in the mica group. Anyway, the stone has some schiller and sparkle and kinda looks like a cross between lepidolite and feldspar. I suppose there could be some reaction to the lithium. Maybe. I have city water. God only knows what is in it, though it tastes better than most bottled water.

I thought it was algae. I'll go out later and see if I have any of that material. I think mine is lower quality than yours but some of it did turn green.

All kidding aside, I don't think it would be a mold. Do you have any silica gel- the kind usd in flower drying? If you do, try dropping in that stuff for a day or two. It should pull any extra moisture out that could come out. Either way, it's a neat cab!

Put it on the dash of your car and see if the heat of the sun drying doesnt change something. If you worry about sun fading warap it in foild.
Mold requires nutrients, algae requires moisture and sunlight.
Has to be a salt reacting with something.
Lepidolite is a lithium ore.
Chemistry: KLi2Al(Al, Si)3O10(F, OH)2, Potassium lithium aluminum silicate hydroxide fluoride.
May also contain rubidium... Strange material. I'm not helpful. Sorry amiga.

very interesting tela alchemical even
you can see where the green is attracted to very specific area in that stone
do have any more of the rock ? do you have any other pictures? pre green?

In terms of weathering/stability (at least as measured by potassium release), lepidolite seems fairly stable, so oxidation or leaching may be unlikely. link: www.clays.org/journal/archive/volume%2018/18-4-187.pdfDoes it smell like mold? Do you have a microscope? Can you see hyphae or spores?

I don't have pictures of the slab. Most of broke up when I preformed it. This was the best I could get from it. Very delicate to work with. But, I assure you the slab was pink, the preform was pink, the cab was pink. Until it sat in a bag, in a bin for a month. So weird. I do have more pictures of the cab, though. Nothing any different from you see in the posted picture. It is (or appears to be and was sold as) a lepidolite with some ruby, some schiller and lots of fine sparkle. There are some dark dendrite type things. The back has a little green, too.

Do you have a microscope? Can you see hyphae or spores? Funny, you posted just as I was magnifying it. I have my optivisors and a 10x magnifying glass. I can not discern anything organic. The color is not ON the stone, but IN the stone. My grandson has a nice microscope (I got it for him for Christmas ) Next time I am over there I can look at it under the lens. I haven't tried bleach, yet.
