D2 Dichroscope with optional holder and neckstrap

Unlike old-fashioned calcite dichroscopes, which only provide fuzzy colors, Professional Gem Tools dichroscopes contain high quality optics that allow the user to actually examine the stone.

Our patent pending design eliminates secondary internal reflections. This provides a clear and sharp image when viewing the stone.

Our dichroscopes have 6.35X optical magnification, allowing the user to view into a stone to see flaws as well as to determine pleochroism. With this feature, gemcutters can easily orient the stone for best color rendition. Both dichroscopes come with a leather storage pouch.

Model D2 Dichroscope: $159.95
The D2 dichroscope is made with a stainless steel casing. It has an effective lens aperture of 11.9mm, which produces a bright image. The D2 also features the finest boron float glass in the filter component providing distortion-free viewing.

Experienced users can even identify the growth lines in verneuil corundum with the D2! Overall dimensions are 39.6mm long x 14.8mm diameter. An adjustable neckstrap with holder is available for the D2 dichroscope (pictured at right) for $12.95.
