Here are some stones I cut a while back... some are really early work.
The purple two on the bottom left are Royalite, an ore/gangue material from a nearby mine in La Plata Canyon. The Royalite contains trace amounts of Platinum on the Chalcopyrite.
Besides the lapis and gaspeite I either collected or traded stones I collected for these. (for the rough material)
Top left blue stones- Lapis
Black/earth tones with tree scenes - Picasso Stone from Utah, I love this stuff
top right - turquoise! All from the SW United States.
Pink stones - the banded pink is rhodochrosite and the solid pink is local Rhodonite (pyroxmangite) I used to mine tons of the Rhodonite, it is local to me.
right bottom, red and out of focus! local red jasper
Yellow - Arizona Serpentine my friend mined, I traded it for rhodonite I collected
Green - Australian Gaspeite; ultra rare and no longer found, this stuff is really bright!
There is a big green calibrated malachite cab and some silicated green malachite/chrysaccolla/azurite. The silicated stuff is great solid material and usually mined for it's copper content. There is a big green stone of that material too...
The white stones are Howlite, it is sometimes called white turquoise.
