HOW TO SPOT A FAKE
There are techniques available to distinguish between a fake and a genuine tanzanite stone and identify gemstone that is genuine:
Hanneman Tanzanite filter, a combination of color filter and dichroscope, is one of the methods to separate synthetic forsterite with tanzanite. When viewed through this filter the synthetic forsterite displays greenish color while genuine stone has a pinkish color. So tanzanite identification using this filter is very easy.
Certification by international gemological authority is a must when buying high grade stones. Certificate must include important data as carat weight, color, cut shape as well as cut grade (quality of cutting), refractive index, color including grade and hue.
Digital refractometer is device used to calculate refractive index of faceted gems. Refractive index of tanzanite is from 1.69 to 1.70 so digital refractometer is one of methods that can be used to determined if certain gem is genuine.
Trichroism can be also used as tanzanite identification method. Genuine gemstone when observed under different light should display different colors. You can examine tanzanite for example under incandescent and fluorescent light and you should observe different colors most of the time if it's real genuine stone.
