That would be a nice little black spinel crystal :inlove:

@rockrat thats what my friend said that I was out with. We were both cheering ?

@wally69 there was a lot of spinel where I found it so possibly. Never found a spinel with that shape though.

Wally could be on the money there, spinel does come in octahedron shape. :Y:
A good find.

[Rockhunter62]

It looks like landfill.

Cheers

Really? it was found up near mt isa mines. Oh well.

Quartz - you should always quote hardness, it is easy to determine (7 for quartz).

I notice a tendency on this site to call quartz with even the slightest darkening to be referred to as "smoky quartz" - most of it I would never call that. This is smoky quartz:

Went for a scratch in Retreat creek The Gemfields qld, wuz lookin for sapphires with no luck, then tripped over this fist size cooked rock. Gave it the vinegar soak.. Any ideas on what to use next. When it is cleaner I am hoping to see some sparkle in the small cavities, with the possibility of cutting in half and finding a geode.

Never been disappointed when out scratching, pink quartz, mica in quartz, black and brown quartz like a licorice allsort. keep the nose to the ground and something will jump out atcha

Soak in Diggers Deck Cleaner from most hardware stores - you don't find it with Methylated Spirits and the other Diggers products, usually in aisle 23 in Bunnings. I think I got mine in Mitre 10 in Emerald.

I was asked by a neighbour to see if I could get some info on these two rocks. I thought this forum was the right place to come. They were picked up from an old tin mine near The Archer River in NQ. They are pretty weighty and have a sheen on them where they are the smoothest. Any thoughts would be appreciated. Cheers Sorry the clarity isnt the best.

Looks like normal ironstone to me Rick.

[kemjak57]

:Y: I thought it looked like iron stone but the weight was what made me question. Might have to crack it open. Some good info in that book. Im a real fan of the coen area. Cheers guys

 

[Goldenred33]

Any ideas what these are ?

 

[Heatho]

Limonite is my best guess.

 

[Goldenred33]

Ok thanks heatho :Y:

Hi

Could someone help me identify this? I was told by the person that gave it to me that its a sapphire but I would just like to know for sure It is around 180mm x 140mm

Thanks in advance

 

[lealucas79]

This is another 1 but I have broken a piece off this 1 to try and get a better idea of what it could be. Its about 110mmx 80mm

This is the bit I broke off
