Great to be back here, Michael was surprised and pleased this forum is back, we went rock hounding a few weeks back with Southerly, to a new rhodonite location in our region that we have driven past many times, and a piece of copper rock rock Michael- mick B found last weekend.

Glad to see you and Michael back Margie..

Trying to figure out what the other elements are aside from the obvious pink colored rhodonite and manganese oxide.  Any idea what the blue and green might be ?

Going to be some really pretty patterns in any cabs you guys cut from that one ..

The copper rock slab I think could easily fall into a chrysocolla category.. I see quartz, azurite, copper, and a touch of malachite..

That rock is quite a mishmash with manganese ores such as manganese oxide, rhodonite, tephorite and possibly some sugilite, as well as quartz and jasper.

Yes we think Southerly is spot on with his description, not sure on the sugilite, the tephroite can be gray, green or a blue green, this piece we cut was from the same block, its very fine grain and the hardest rhodonite Michael has cut, above 6.5, due to the quartz jasper mix ?.

It all comes down to how strongly the atoms are bound together. 

Can not wait to see a cab or two from this.. The patterns are really nice.

After reading Sotherly's description, I was a little concerned for you about possible undercutting.  But with your description for a consistant 6.5 through out, it will be excellent cabbing !

If you ever would like to sell a slice, let me know...
