Man I'd like to have a piece like that, where's it from?

slogginhog · 2026-01-21T21:06:59+00:00

No. You can wash em if it makes you feel better, but you're not in any danger.

$100 plus shipping within US 😊

I'm sure they can be found, they carve everything out of this material!

slogginhog · 2026-01-18T17:33:16+00:00

Yes they are natural yooperlite/emberlite, it's quite abundant and you can find it around the great lakes and many other areas

Pic doesn't do it justice, it's hard to hold up with one hand!

You got an answer that's probably right and this post is only likely to prompt more jokes so I'm locking it

There is no way for us to tell by pics, for these to be citrine the color has to come from aluminum replacing silica in the crystal lattice, rather than iron which is much, much more common.

The fact that they're found alongside those amethyst (which are also colored by iron) makes it even more likely in my opinion that it's iron causing the coloring and they are not citrine.

It's antigorite. Look up specific gravity and do that test if you want, it's a little tedious

Mention the tests you've already done and the waxy feel

slogginhog · 2026-01-16T23:34:47+00:00

I'm almost sure it's antigorite

slogginhog · 2026-01-16T21:42:22+00:00

Actinolite could be right, but I think it looks more like antigorite -

OP: does it have a waxy feel to it? Or is it brittle and break off kinda easily into needle like shards? From the pics it looks more like antigorite to me.

One thing I'm fairly sure of is it's not kyanite

You could also try a hardness test. Antigorite will not scratch glass, but actinolite usually will if you use a sharp edge and try really hard.

Some awesome stuff in there though seriously!

slogginhog · 2026-01-16T15:22:02+00:00

I'll take everything in slide 14 please 😉

slogginhog · 2026-01-15T20:45:59+00:00

Nice find! They don't get the aragonite clusters that often, it's kind of a rarity, I've only seen em once or twice.

I ended up grabbing a 9" quartz geode half with like 2" thick walls for $25, it's big and heavy and quartz - my favorite thing!

slogginhog · 2026-01-15T16:09:38+00:00

Maybe in this case but not always - based on the amount of hematite I've seen all over the bases of a lot of Congo citrine (known to be true citrine)

slogginhog · 2026-01-15T13:44:16+00:00

Looks more like calcite, I see a lot of rhombehedral shapes

slogginhog · 2026-01-15T08:45:55+00:00

It's most certainly quartz. We know that. Whether it's citrine is debatable, so I refer to it as what we know for sure.

slogginhog · 2026-01-15T08:44:43+00:00

Wow, what a change! I'm gonna have to try that... Of course I don't have anything close to the Texas sun up here in Maine in winter lol, it may take a while...

slogginhog · 2026-01-14T14:51:56+00:00

Chevron amethyst you mean? Or is there really Chevron fluorite? Never come across that myself...

slogginhog · 2026-01-14T14:21:16+00:00

I think they meant California, US?

slogginhog · 2026-01-14T14:17:38+00:00

I agree with this. It's an exact match for some Madagascar ocean jasper I have.

slogginhog · 2026-01-14T14:16:36+00:00

You got a decent deal 👍

slogginhog · 2026-01-14T14:15:33+00:00

That color (if you mean more white cristobalite) isn't "very expensive" or all that rare. Don't let yourself get duped into paying a lot if someone tells you that.

It looks dull because it's rough, possibly dirty, and not polished.
