The CL-181 Gemological refractometer is a low cost, lightweight measuring instrument used by jewellers and traders of gemstones to measure polished stones over a refractive index range of 1.30 to 1.81 RI. The instrument can also be used to identify whether a particular stone is Isotropic or Anistropic (uniaxial or biaxial). Gemological (Gemstone) Refractometer is your primary and most powerful tool in gemstone identification. As with a typical critical angle refractometer, it will measure the Refractive Index of faceted stones. It comes with Refractometer Index oil, Mini Flashlight, Storage Box, Polarizing Lens and Leather Carrying Case! Have the most essential and powerful tool in identifying gemstones. Features: Can identify singly & doubly gemstones quickly and accurately Uniquely desigend, low battery consumption and portable Powered by FREE four 1.55V Batteries Approved by strict quality and safety standards for long and trouble-free life Guaranteed high quality and accurate testing results Brand new and unused Specifications: Measuring Range: 1.30 – 1.81 RI Minimum Graduation Value: 0.01 RI Dimension: 30 x 70 x 130mm Weight: 400g Accessories included: FREE Leather Carrying Case Small Vial of 1.800 Refractive Index Oil (If you add USD12.00 to order, you will get a bottle of index oil in extra) Polarizing Filter Monochromatic Light Filter Provides a unique Designed Mini Flashlight for illumination which includes the 4 1.55V(AG13) batteries Storage Box Refractometer Index Reference List (For 77 common gemstones, i.e. Calcite, Jadeite, Quartz etc.) User's Manual   Operating Information : Lay the instrument on the worktable. Open the upper cover. Drop some of the special refractive oil onto the surface of the prism by a thin glass bar. Make the ground surface of gem to be measured close to the prism, press it lightly to make refractive oil distributed evenly between the two surfaces and close the upper cover. Align the entrance filter of refractometer and light source to the make luminance of viewing field even. Move eyepiece up and down and adjust diopter appropriately. Now you can see a light/dark boundary in the viewing field. The gradation on the boundary shows the refractive index of a gem. The index of double refractometer of gem can be measured precisely because the filter of the refractometer can eliminate the phenomenon of dispersion. Warranty: 2 years warranty (24 months) The Product Included : Refractometer Index Reference List i.e. Jadeite Refractometer Index : 1.660 - 1.680 Reflective Index on PRM / PDT : 32 - 36 back to top 2) Handheld Darkfield Loupe with Flashlight (CLMG-7201): 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 of inclusions and to determine 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. Specifications: Darkfield Loupe Magnification : 10x For grading gemstone, Using dark Field lightning for inspection of inclusion, internal cracks, surface marks, etc. Viewing field (lens) : 18mm in diameter Length : 10mm Handheld LED flashlight Length 156 mm LEDs x 3 Power : AA x 2 (not included) Accessories included: LED Flashlight Carry Pouch Warranty: 2 years warranty (24 months) The Product                         back to top 3) 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. 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. Rubies (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. 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.

It is use to view the colour of a gemstone, either by shining a light (pen-torch) through the stone into the spectroscope if the stone is transparent, or by viewing its reflected light if the stone is opaque. inside you'll see a spectrum (a rainbow) which might be interrupted with black or white lines, it is the pattern of these lines you must learn to recognize. For gemmologist it is best at detecting iron and chromium and for non-gemmolgist 'diamond simulants' YAG and Cubic Zirconia give spectacular spectra and so too does some Zircon. Though, other gemstones are a bit more difficult to detect. Features: Large diameter eyepiece aperture facilitates comfortable viewing of the single, large and bright spectrum which is centrally placed in the field of view. High quality optical components ensure that absorption bands show up clearly. The linear spectrum is generated by a particularly bright transmission diffraction grating of around 600 lines/mm. This is a top quality instrument giving a brilliant spectrum. Specifications: Length: 55mm Diameter : 22mm Material : Aluminum (Heavy Duty) Inside Instruction : Raster type Accessory included: Leather Carry Case Warranty: 1 year warranty (12 months) The Product                           back to top 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. Trichroic gems can also be distinguish and will reveal three colors if the stone is viewed in three directions perpendicular to each other. Specifications: Type: calcite Diameter: 15mm Length: 60mm Body: Metal Accessories included: Leather Soft Case User Manual Warranty: 2 years warranty (24 months) The Product             back to top 6) 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 Moisannite and detecting strain in diamonds.
