Stibnite spray? I think....... Biotite? may-be as I have a lump here and it looks simular but not in that shape. Has it got glittering bits in it?... Is it heavy?... Is it fragile? Location found will help... When you scratch it on the back of a Tile, what colour dose it leave...

Ahhhhh too many Q's.... my head hurts...
See Streak testing here... and other methods...

It does have glittery bits in it. Found in the ocean at esperance wa quite hard

 

[Heatho]

Actually looks a bit like schist to me, could be wrong though.

 

[shakergt]

Does look a lot like schist

 

[LONEWOLF]

I did an image search last night and it came up Schist.... But it has some strange structure on the top of the thin end... That's why I thought Sibnite spray, but as you found it on the beach, I don't think it is a Stibnite Spray....

Anyone know what this is.Feels and breaks like glass.

 

[Heatho]

Giant Sapphire mate!

Nah, probably green obsidian (volcanic glass) Smoky. Wish it was a giant Sapph though.

I've seen schist like that before when Shauno (Syndyne) showed me an emerald specimen in it's host rock which was schist, the specimen was from I think the Aga Khan mine Western Australia.

Yer mate just showed a geo and he said the same thing :Y:

Hi Smoky B, bet that one made the heart miss a beat or two.
Cheers, SinHof.

It did mate......I knew it wouldnt be worth much though as I'm just not that lucky. But there was just a little bit of hope.

It certainly has an unusual shape on the side of it... My guess is the same as Dihusky... Garnet.. could also be a Zircon... Pics alone are sometimes hard to tell tho...

LW....

I suspect garnet

A schist of some type, probably with biotite but perhaps other minerals as well.

 

[user 4386]

Can anyone tell me what this is please it was found in Tasmania

Maybe Agate

Looks a bit like a chalcedony geode (from a volcanic rock perhaps). Need more info.

 

[user 4386]

Hey everyone,
I found a stone when I went walking a few weeks ago in Lamington National Park. I would love your help identifying it.

Do you know what it is?

Thanks!

Looks like botryoidal chalcedony

Ditto - perhaps within chert rock/

 

[LONEWOLF]

Hmmm the National Park Fossicker... :/

LW....

 

[Dihusky]

This is an unusual one, the stone weighs 3.35ct, has an SG of 3.24-3.40, I'v measured a few times and being small get a bit of variation on my scales, 0.05ct can make a bit of a difference in the SG figure, it's gold to coffee colour and can be scratched by quartz.

This is pointing me in the direction of Enstatite, maybe a clear version of Bronzite? It was found in Australia and according to Mindat there are a few recorded meteorite craters where Enstatite can be found.

Anyone got any other ideas?

 

[Theduke]

Axinite maybe

 

[LONEWOLF]

If it was found in Qld, I would say 'Fourexite' ... {)

Very unusual Dihusky.... :Y:

LW...

 

[Dihusky]

Axinite maybe

Interesting, certainly Moh & SG compare well, not sure about the colour though, turning the piece there is no evidence of purple. Also had a look at the surfaces and there is no evidence of cleavage planes, very irregular style fracturing, indicating it might be quite brittle which does fit your suggestion.
