NW Tasmanian (Table Cape region) sapphire and zircons
Above are some largish well-formed examples of Tasmanian stones sent to me for cutting a while back. The 4.9 ct sapphire pictured above is a nice example of the dogs-tooth shaped crystal habit.
I examined the sapphire above and tried to determine the best orientation, taking into account inclusions/cracks etc.
I decided that the orientation above would 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 was the selection.
Final polish on pavilion (I know I’m really slow, lol)
On to the crown..
Final polish ahead.
Yield was 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!)
