Umba Sapphire and Morogoro Spinel

12/08/08 18:35 Filed in: Latest Cut Gems
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.

Two new stones this week. The first is a blue Sapphire from Madagascar.

This second stone is a white topaz from Nigeria cut in a snowflake design with frosted facets. The frosting shows up better in person, especially with a darker background. Makes for a fun interesting stone.

Sapphire Recut

19/05/08 20:02 Filed in: Latest Cut Gems
This is a picture of a recut sapphire. I didn't get around to taking a before picture, but it was the typical native step cut. Lopsided, poor meets and a deep belly along with a window.
For the recut I did a concave cut to bring out some more color from a light stone.

The finished stone is 3.12 ct.
