With its user-friendly design and clear instructions, this filter enables accurate observation of dichroic colors, ensuring that you can confidently identify genuine Tanzanite stones. ## Description Characterization and identification of Gems by the use of color filters has always been an appealing approach because of its affordable simplicity and the ease of examining multiple specimens. Featured here is a combination Color Filter and "luggage tag-style" Dichroscope Filter (facsimile shown in 2nd photo) which allows one to distinguish genuine Tanzanite from all of its imitations, such as blue synthetic Forsterite. ## Features - 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. - Dichroism Test: Observe the illuminated stone on the white viewing surface while holding the Dichroscope filter just above the stone, at least 14" from the eye. Move the filter from side to side across the black strip dividing the two transparent polarizing filters. Change the position of the stone and the filter movement several times so as to confirm your observations. Note any color changes observed.You should be concerned with the "body color" of the gem as seen through individual facets. ## Product Details - **Brand:** Hanneman - **Material:** Stone, Tanzanite - **Coating Description:** No Coating - **Photo Filter Effect Type:** Color Correcting - **Water Resistance Level:** Not Water Resistant - **UPC:** 753807504171 ## Images ![Tanzanite Filter/Dichroscope Filter - Image 1](https://m.media-amazon.com/images/I/91WPmR1YScL.jpg) ![Tanzanite Filter/Dichroscope Filter - Image 2](https://m.media-amazon.com/images/I/31Q+N4XUlBL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ not real good *by K***E on December 31, 2023* not very useful for me ### ⭐ Scam *by L***B on March 15, 2021* This was a waste of money. I took to a gemologist and this said the tanzanite was real and gemologist showed me it was not. ### ⭐⭐⭐⭐⭐ So easy to use! *by G***Y on December 6, 2019* I loved that the filters came with charts and descriptions of expected images of the gemstones!
