Gemology/Jewelry Microscope

Gemology/jewelry microscope is a microscope used to observe some of the invisible details on the surface and inside of jewels, gems, and various crystals when observing.

The surface features of jewelry, include scratches, breakage, color circles, etches, cleavage, cracks, split faces, polish, etc.; internal features, include the types of contents, the inclusions, growth lines, double crystal lines, textures, ribbons, and the doubling of the rear facet edge of the gemstone etc. For these features, it is very necessary to use gemology/jewelry microscope for observation and identification, and it has also an extremely important application in diamond grading, making it an essential instrument for gem identification.

For general jewellery observations, the defects and features after 10X magnification are considered the basis for economic evaluation. For jewelry microscope, stereo microscope is generally used, with a magnification of 10-80X or higher, and more detailed features can be seen. According to the characteristics of jewelry observation, jewelry microscope requires large depth of field, which can present the diamonds, jewelry interiors and their polyhedral structure, with true color reproduction effect.

Due to the different types of gemstones being observed, jewelry microscope needs to be matched with a variety of light sources and illumination forms. For lighting, usually full-color light is used, its continuous spectrum reflects the true color of the jewelry, and can achieve good observation effect for transparent, translucent and opaque object. The lighting methods of gemology microscope mainly include:
Reflective illumination: use the reflector lamp above to observe opaque or translucent objects, as well as the surface features of the gem, such as the ports, cleavage surfaces, ribbons, and gemstone grinding etc.

Transmitted illumination method: the transmitted light at the bottom is used to observe the internal features and defects of the gemstone. Usually, the bottom light is a diffuse reflection light source with dark field illumination, and there is a switch button, in the center of the bottom light, there is a black disc "light block", used to switch the light and dark field of view conversion of the bottom light.

Transmitted bright field illumination: the transmitted light can penetrate the interior of a gemstone. Against a bright background, details within the jewelry such as inclusions, textures, growth lines and ribbons can be seen clearly.

Transmitted light field dark illumination: after the bottom light is blocked by the "light block", it cannot directly enter the field of view of the objective lens, forming a diffuse reflection illuminating the gem around it, which is convenient for observing the inclusions, cracks and growth lines of the gemstone, and seeing the details that are not easy to find in bright field.

Spot light illumination method: adjust the aperture diaphragm (aperture) to a position close to the smallest suitable size, so that the bottom light is reduced into a dot shape, and the light penetrates from the bottom of the gemstone for illumination, so that the ribbon and the structural feature points of the gemstone are more prominent.

Horizontal illumination method: use a sidelight to illuminate the gemstone horizontally from the side, so that the gem dot-like inclusions, textures, and bubbles etc. present striking and bright image under the vertical direction light illumination.

Masking illumination method: use the bottom light bright field for illumination, insert an opaque light barrier in the field of view to increase the three-dimensional sense of the internal feature points in the black and white boundary of the light, which helps to observe the growth structure of the gem, such as the bending growth lines, double crystal lines, etc.

Scattering illumination method: use the bottom light bright field for illumination, place a tissue or other translucent material on the light source to make the light softer, which helps to observe the color gamut and the ribbon, especially to observe the diffusion treatment effect of the gemstone.

Polarized illumination method: under the bottom light source and the objective lens, a polarizer piece is added respectively to produce a polarizing effect, which can help to observe the interference effect, pleochroism and the optical characteristics of the gemstone.
