Dichroscopes XHST1024

Calcite Dichroscope shows whether or not a stone is dichroic (reflects 2 colors). This can be helpful in differentiating stones of the same color from one another. Dichroscopes can be useful with identifying gemstones that are still in the rough and when stones are set and difficult to get to with other instruments.

Hand Held Polariscope XHST1023

Chelsea filter XHST1025

This Chealse filter is designed to transmit only deep red and yellow-green light (best obtained under strong electric light). Just hold the filter close to your eye and look at the stones. Multiple stones can be viewed at once. It is helpful with identifying certain red, blue and green stones. Chelsea filters are primarily used for spotting fakes added to colored stone parcels and mixed in jewelry, and to differentiate emerald from emerald look-alikes, it is also useful for checking aquamarine and sapphires.
With the filter emeralds usually appear distinctly red or pinkish in color, while most imitations remain green. In rare cases certain emeralds, most notably from South Africa, may not show any pinkish color at all. A synthetic emerald will react the same as a genuine one.

Ruby filter XHST1026

(both genuine and synthetic) appear brilliant red under the filter. Synthetic blue spinel appear yellow-orange or pink while aquamarine and sapphires appear green or green-grey.

Dark field loupe XHST10X-DFL

(Hand held 10X dark filed loupe c/w hand held torch)

The darkfield loupe is a small instrument that provides 10x magnification as in a standard loupe, with an important added feature: it is combined with a specially constructed area that enables
you to view a gem against a black background with strong lateral lighting. This is called darkfield illumination, the reason why this instrument is called a darkfield loupe. This type of lighting environment makes it easier to see certain types more precisely what they
are. Especially valuable for colored gemstone buyers because seeing inclusions clearly plays an important role in separating one colored stone from another. The darkfield loupe is an important and essential tool in examining colored gemstones, for anyone buying diamonds or diamond jewelry and in viewing many fracture-filled diamonds that
are currently circulated worldwide. A fracture-filled diamond also known as clarity enhanced diamond, is a diamond which contains a crack or cracks that have been filled with a glass-like substance to improve the overall appearance of the stone. Using the darkfield loupe is the easiest way for most people to spot fracture-filled diamonds.
