Two new stones today. The first is a Sapphire from Umba Tanzania. This one I cut in a emerald type shape, but not a traditional emerald cut. What's nice about these Umba sapphires is that they are all natural, no heat or other treatments. They also show a color shift depending on the lighting. This one goes from a violet to purple depending on the light.



The next stone is a Spinel from Morogoro area in Tanzania. This one has a real nice color and a nice size. It's 3.32 cts. and measures 8.5 mm.
