I was farting around in Photoshop and was planning to post a few ramped images on Facebook, but I thought you all might enjoy these - just for fun

Took me a moment to figure out how this works but it's pretty ingenious.  I've never seen this one before.

here is what i would look for in a perfect amethyst.  Nice deep purple, but not so dark as to be opaque.  You should see red and blue flashes from incandescent light as it hits the facets.  Even color throughout the stone.  The cut should reflect all the the light through the table.  No "windows" that let you see all the way through the stone when looking through the table.  No visible inclusions. A girdle that is appropriate for the stone size.  No big band around the stone and no knife edge shaped girdle.

I would like a sphere of pietersite, nice work!
Here is a piece of Nephi petrified wood I collected a couple weekends ago. This is totally healed, but you can see it was tortured at one time! A little darker than I hoped for. Polished both sides take your pick.

Found this interesting tip for determining specific density - I'll give it go and report back

Totally possible.  A crack is a weak spot in the stone.  Heat, the vibration from your wheel, the stars aligning the wrong way ....

you could always call and ask... But I like their blades for tougher rocks like jasper, agates, etc. (except jade).

Actually, it does not seem to have a pattern - just a bunch of small sploches (?)

Thanks all!
I just cut the opal at the crack. I  could have sworn it was not an open crack when I started polishing, but the heat could have had something to do with it opening up?
