The polarimeter is one of the GEM instruments. It can determine whether gems have single or double refractive. It is technically used for testing the refrangibility of the gem, through this polarimetry can more easily judge whether the gem is real or bogus, at the same time, the gem can...

The AMZINST Polariscope is used to test the optical properties of gemstones and determine whether a stone is singly refractive, doubly refractive, or is an aggregate. Doubly refractive stones may be divided further as to whether they are uniaxial or biaxial. The polariscope may also be used to detect pleochroism in...
