Re: My new obicular poppie jasper
Thanks for the reply’s. Great to see material from other sites. That Andamooka matrix looks good. There is a method that does not use acid now and it gives a darker background. Olive oil in vacume chamber. Wrap opal in Alum foil. Put in beach sand in small container and cook at around 250-300 •c for...

My new obicular poppie jasper
I found this deposit around 2 years ago in my region of Tamworth NSW Australia. The colour is caused by hematite and heaps of magnatite black base the poppies are jasper. Silica.

Re: Natural Andamooka opal
Thanks. It polished easily and needs no sealing. No pitting.I was told it could be oolite opal. It has little black and brown spheres in it.

Re: New Zealand Jade carving
Thank for the great comments. This jade was very hard. Easily 6.6 about as hard as nephrite gets. I used diamond paper on the smoothing stages. To slow with carbide sticks.

I was recently given a piece of what I thought was Andamooka treated matrix opal but the stone has a natural dark background and the limestone- sandstone bade is very fine grain.

Re: My rhodonite chain
Thanks rocks2dust & PinkDiamond, this carving is the most challenging to date, the sanding process is very demanding, I will finish on 50 K diamond if I ever get there, some more pictures of early progress, I carved it like they do a wood chain.

My rhodonite chain
