A combination Color Filter and Dichroscope which allows one to distinguish genuine Tanzanite from all of its imitations, such as blue synthetic Forsterite. |
-
Tanzanite-colored synthetic Forsterite shows distinct dichroic colors similar to those of Tanzanite. Nevertheless, these two materials are easily differentiated by viewing through this color filter dichroscope. Synthetic Forsterite exhibits a greenish body color, while Tanzanite shows a pinkish-orange color.
-
Only Tanzanite shows both this pinkish-orange color and the correct dichroic colors. Regardless of appearance through the color filter, all other presently known simulants fail to display the proper dichroic colors when examined with the polarizing filter dichroscope.
-
Instructions: Place loose stone table down on the white viewing surface that comes with the kit. Illuminate with a bright incandescent light. Through the filter, the viewing surface should appear a dim pinkish-gray color. Now hold the color filter as close as possible to the eye when viewing the test stone. Note the apparent color of the stone, consulting the included table.
