These were two stones I cut a while 1+ years ago..right one is spess garnet and left one is tourmaline. They were not cut as matching pairs but both turned out roughly same size and had same SRB cut. Camera wasn't angled properly so those dark areas in the middle are only tilt windows. Small like 1/2ct each.
this pakistan moonstone I may have posted before but it was a pic in hand and not a setup shot..cut it a long time ago 3+cts.
Here is a ampa tourmaline(dravite) from India that gsellis cut a while back. Brown is not the best color but what do you expect from non-chromium bearing dravites ;D. These have the widest range of colors I have seen from a deposit oif dravite tourmalines. Very odd to have such a cornucopia of hues in dravite. These range from green, brown, cognac, yellow, red, and orange but always with brown as primary or secondary. Some of the other ampas that you can see cut are under Ricks "New Camera" thread. In this one you can see in the last picture(out of focus) the fairly strong green when it's tilted down the opposite axis(pleo.)
Look how strong the green shows with the pleochroic property
All photos taken under 6500K bulb with top spess and tourm. taken under 6500K with filtered use of 4700K as well(adds warmth). Pics have not been altered in any way save for cleaning up dust spots on surface the stones are sitting on.
