These two tourmalines are perfectly matched in shape, size, color, because I cut them from the same source of rough crystal. They are a very pastel green, almost white, but with screaming brilliance, due to my precision cutting, without any hint of a light leaking window. They would be perfectly suited for matching earrings. The picture is taken with daylight, cool light.

This tourmaline is cut in an opposed bar cut, which has 7 facets running the width of the gem on the top, and 6 opposed facets running the length of the gem on the bottom. When you point this gem toward the light and rock it back and forth, you will see a rippling of the brilliant facets along the length of the stone. This picture was taken in daylight, cool light.

This tourmaline is a very complex cut, quite unusual, and difficult to execute. It has a diamond outline (8 sided girdle), but not with a typical emerald cut, step cut pavilion. Instead, it has a pointed, deeper Barion cut pavilion, which requires a larger, deeper, more rare crystal to execute, but provides even more brightness. The first picture was taken in daylight, cool light. The second picture is taken with warmer evening light. So it seems to be something of a color change tourmaline, with a beautiful, unusual cut. I don't think I have ever seen this color combination before in any gem species.

Variety: tourmaline, bi-color
Carat weight: 0.87 cts
Measurements: 6.7x4.8x2.9mm
Color: green-orange

Bi-color tourmalines that are eye-clean (1X, no magnification) are close to non-existant. The chemistry that allows the two colors, seems to upset any orderly atomic arrangement during the change of color. This picture, shown at 2X, should show visible imperfections. It doesn't. But if you tilt the gem somewhat, you can see very small linear dislocations at one certain angle. So let's say it is VERY CLEAR for a bi-color tourmaline, but not eye clear. I reject 98% of bi-color crystals that I examine, because the finished gem will not show the clarity that I desire. The picture was taken in daylight, cool light.
