1) GEM REFRACTOMETER with Built-in Light Source and Index Oil (GR-701):
The GR-701, commonly known as Gemstone Refractometer, is the primary and most powerful tool in identifying and authenticating polished precious and semiprecious gemstones and also observing the optical properties and the structure of gemstones. This model is just as good as the expensive models used in gemological institutes, it has a built-in light source and with the aid of the Contact liquid (RI Fluid), which creates an optical contact between the glass and the gemstone, you can measure or test the Refractive Index of faceted stones, its transparency or opacity, and its beauty, durability and scarcity.

2) Handheld Polariscope with Flash light (CLMG-7202):
The polariscope is used to test cut or rough gemstones. Allows two polarising filters to observe the structure and optical properties of precious stones or minerals. It visually shows if a stone is doubly or singularly refractive. It can also be used in identifying Moissanite and detecting strain in diamonds.

3) Handheld Darkfield Loupe with Flashlight (CLMG-7201):
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.

- Size: 98mm x 58mm
- Diameter: 24mm
- Power: AAA battery x 3 (Included)
5) New Calcite Dichroscope (CLMG-7208):
Dichroscope show 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. Light entering the dichroscope is broken into two polarized rays that have vibrational directions at right angles to each other. The two images in the dichroscope represent the polarized light and the pleochroic colors signifies doubly refractive stones except if the stone is viewed thru the optic axis. Single color in the dichroscope represents singly refractive stones.
The advantage of the dichroscope is that the two pleochroic colors that may be characteristic of a given direction in a doubly-refractive gem are seen side by side. If no dichroism is identified in the first assessment, the stone can be turned and viewed in other directions.

6) Big Prism Spectroscope (CLMG-7204):
This Big spectroscope breaks up the light that is being transmitted from a gemstone to its spectral colors. The process allows the gemologist to see the various wavelengths absorbed by the gemstone. Thereby allowing the gemologist to know what elements are contained in the gemstone that are causing the absorption. Making this as one of the most important tools in identifying gemstones.
Spectroscopes allows you to analyze a loose or mounted stone's spectrum. They help distinguish naturally colored diamonds from those that have been irradiated and help to distinguish natural stones from synthetics by the stone's selective absorption of certain wavelengths.
- Length: 130mm
- Diamter: 20 mm
- Material: Aluminium (Heavy Duty)
- Inside Instruction: Prism Type
7) Chelsea Filter (CLMG-7300):
An essential device in identifying colored stones. While it was originally intended to rapidly differentiate between genuine Emeralds and the pastes and doublets which resemble them, it also is a valuable aid in identifying other colored stones, as well. Designed to transmit only deep red and yellow-green light, and the best results are obtained when stones are examined under a strong electric light. Just hold the filter close to the eye with the stone or stones (for a number of stones can be examined at one time) receiving as much light as possible. Under these conditions, Emeralds (absorbing in the yellow green) usually appear distinctly red or pinkish in colour, the actual tint varying from merely pinkish in the case of pale stones, to a rich almost ruby red for better coloured specimens. On the other hand, most imitations of the genuine stone (pastes, doublets, soude Emeralds) retain a green appearance. A helpful tool in identifying certain red, blue and green stones.
This Chelsea color filter has a glass filter which gives better clarity, reduces distortion and provide better protection from humidity. With Chelsea filters you can differentiate the genuine emeralds from the fake once, as well as checking the authenticity of aquamarine and sapphires with comfort and ease.
