Gem Silica has blue in the color and this is what makes it valuable. Calling mtorolite gem silica, with knowledge of the truth, is frankly fraud. Someone along the line knew this and that person is a criminal.

Is anybody sandblasting actual Australian chrysoprase?

I have a nifty piece of intersecting veins, bit smaller than a soccer ball. A pressure washer removed lots of loose rock/mud.

I'm thinking about using an airpen to prep a face and the polish it, would be an insane display piece.

Hints, tips, kinks, or kinky hints?

Frantic Tumbler:  I would keep part of it natural with the rind and then face one or more sides and polish them up.  That way you have quite a contrast between the gel green polished faces, versus the natural looking rind sides.  I think its interesting to see how gems look when they come out of the ground, before they are polished or faceted.  Knowing the lack of common sense of some people, i would guess that there are some people who think that gemstones come faceted out of the ground.  Even knowing about mining and seeing it first hand, its often eye opening to see what comes out of the ground before it is processed to its final state.
