NW Tasmanian (Table Cape region) sapphire and zircons
Above are some largish well-formed examples of Tasmanian stones sent to me recently for cutting. The 4.9 ct sapphire pictured above is a nice example of the dogs-tooth shaped crystal habit.
I have been examining the sapphire above whilst trying to determine the best orientation, taking into account inclusions/cracks etc.
I think the orientation above will give the cleanest stone with the highest yield – so many factors involved in creating the best final product. A rectangular cushion cut, the Tsunami 311, as per this post is the selection.
Final polish on pavilion (I know I’m really slow, lol)
On to the crown..
Final polish ahead.
Yield a little lower than I would have hoped at the start, however this is a really clean stone as a result, great colour (and great cut too I must say!)
