A jeweler sent me the oval Tanzanite pictured below for re-cutting. They didn't like the cut on the crown and they also wanted the shape changed from oval to cushion becasue cushion cuts sell better.
Below you can see how I did the re-faceting.
This is what the Tanzanite looked like when I received it.
It was oval in shape and had a small window.
This close up view shows the bar cut facet pattern on the crown.
The jeweler wanted this changed into a brilliant style of crown in the process of changing the shape.
I am shaping the Tanzanite by hand on my faceting machine.
You can see that I have finished shaping the stone to a cushion.
You can see the new pattern that I am cutting on the pavilion.
I have cut all of the facets. Uou can see where I have polished some of the facets near the culet but other facets are still frosty looking from the cutting process.
You can now see the finished cushion Tanzanite.
The window is now closed and you can see how much more brilliant this stone is than before the re-faceting.
With the stone face down, you can see the facet pattern on the pavilion.
Here you can see what the end facets on the pavilion look like.
