A dark-red Namanga garnet at 2.99 cts. Excuse the dirty stone.
And a little 1.9 cts emerald is up for a recut, just a teaser, its quite light in colour but very clean for being emerald.
It's just roughed in on this pic, by the way. I'll get a before-after set of pics for fun.
DD, the "stratified" look is an optical illusion due to the cut.
Nah, not shoe stringing. It is set on a handpiece of a raytech shaw (faceting) machine.
I can't go by the common means of choosing a cut. I have to make one up as I go. That's what the paper is for, writing down angles and indexes.
The colours are references for angles, so I knew what original angles was used and how low I had to go to get any reflection but still save weight.
I'd not say an eye opener, but pretty cool. It is very dark in colour.
You mean optic axes? I don't worry to much about that unless it results in ugly colour-blending.
If I have crystals, yes I can tell where the optic axis are on some minerals I know inside-out. Otherwise it can be identified with a polariscope where the optic axis is.
