⭐ Gemstone & Mineral Show n Tell

It looks quite dark and with a few cracks.
Not sure it is worth faceting, try to take a picture on a piece of white paper without backlight.
If it looks like the first picture, not a stone to facet in my opinion.

Show it to a faceter to be sure, but from the pictures you posted you'll get a dark stone that won't be worth the money if you pay a cutter to facet it.

Annual trip out to O'briens Creek was a success. Yielded approx. 753 carats of topaz and a nice big honey coloured smokey. The big triangle topaz is 193 carats, deep and very clean. I am planning a trillion style cut for it as this best suits the shape of the rough. Possibly a Portuguese style trillion. Any suggestions on a design would be greatly appreciated!

Quartz crystal with some Pyrite attached found a few miles underground.

Sorry about the pic quality, but would anyone like to take a guess? It's a bit cloudy but very cool shape. I'm thinking quartz. Thanks for looking

Hi Bezza, Kinda looks like a diamond crystal to me. Can you post a pic with some better light.Did you find it yourself?

I'll try and post a better picture if possible.

looks like the shape of a spinel crystal

Spinnel or diamond, prolly spinel

Best I can do with this phone, very cool shape regardless.

Fluorite.........?

I honestly have no idea, not super clear it's a bit cloudy if that helps, but can be seen through. Very angular, it has six edges and is pointed at both ends. From what I've found on 6 sided gems I'm calling it as quartz. Thanks for looking anyway

Looking at those new pics definitely looks like a quartz crystal.Double terminated light smoky quartz.

Quartz, if it's small, if it's around 3mm in size, I see these all the time in certain areas Sapphire hunting. Sapphire bend has heaps.

Termination ,quartz crystal

Time for a hardness test mate! Very nice XL anyway!

I've seen a lot like that from sb, my guess is quarts but the area is known to have produced diamond as well

not much i can do with it but nice colour. Found at Andamooka public noodling area
