Ok, here we go.
Let me start by saying thanks to Bobby1 who sold me this challenging slab eons ago. Due to the alignment of the fibers (original cut) and the thinness of the slab, I never dared to challenge it. Now I have grown a bit, so I finally I dare to get carving.
As said, one slab, 3 challenges on 3 different platforms.
Namibian Pietersite, "The Slab"
Cut-offs and preforms, wet
Done. The smaller cab is the easier of the two cabs, as its small, so realigning the fibers to get all round effect was rather easy. Has full colour-range head on, as well as from most angles. This bigger one, needed an extra day of rubbing away on 2000 grid paper to get more chatoyancy into a head on view. Still needs an angle to get the full effect, but it turned out quite reasonable. Like the intense colour, and once one sees the effect its smoth as silk.
Colour changes with light-source, but overall its a bit more intense to naked eye than in pictures.
Here my fav picture thus far
Thanks for looking, Kurt
