The gem gravel of Tanzania produces some of the most beautifully colored sapphires found.
The stone on the left is the most incredible copper/peach color I have ever seen. It was actually the core of a purplish stone, I cut away about 1/2 of the stone to get to this core.
The shield cut sapphire gem on the right was a quick project, just something I wanted to try.
The pictures below shows some color-change Tanzania sapphires, between purple and violet. These stones were supplied courtesy of JazzanJewels.com

I rough cut this material with a 360-grit plate, followed with a fine cut on a 1200-grit plate, and finished with a 14k polish. Remember to cut slowly and use plenty of water.
Sapphire [corundum] has a hardness of 9, making it excellent for any jewelry use. Sapphire's high refractive index means that I can use shallower angles for thinner pieces of rough.
