Dual Light Source Switching

Yellow light has good penetration and can reveal the internal cracks and impurities of jade

White light has good color rendering,and can help the user see the true color of the gemstone.

General Information

A gemstone polariscope is a commonly used method for testing gemstones.It uses a polariscope to detect the rotation and birefringence of light in a material,thereby determining the properties and authenticity of the gemstone.

It is mainly used to distinguish between homogeneous and non-homogeneous gemstones and crystalline(cryptocrystalline or microcrystalline)aggregates,and to identify abnormal birefringence in gemstones.

It can be used to determine the axiality of gemstones and to check their pleochroism.In specific situations,with the help of a conoscope,the interference pattern of the gemstone can be observed to determine its axiality.
