Conoscope for Viewing the Interference Figure of Gem and Jewlery
Description:
In gemology, we use a conoscope to determine optic character in anisotropic gemstones. The conoscope creates a 2-dimensional image of the 3-dimensional interference in a mineral.
Although determining the optic character with a conoscope is a fairly easy procedure, finding the interference figure itself is not. The interference figures always appear around the optic axes of minerals.
The simplest way to find an interference figure is to rotate the stone under the polariscope, in every possible direction, while looking down the analyzer until one sees a small flash of colors appear on the surface of the gemstone. When that flash of colors is found, fix the stone in that position and hover your conoscope slightly over it. Now, while still looking through the analyzer, you should see the color flash transform into a rounded 2-dimensional image.
This image in uniaxial stones will appear different from the image in biaxial stones, each having its own characteristic pattern.
Applications: Gemological Laboratory, Gemology school, Jewelry industrial
