GIA Gem Instruments Authentic GIA Polariscope

Description

This is an authentic GIA Gem Instruments Polariscope. This instrument is used by Gemologists to test the properties of gemstones and determine weather a stone is singly refractive, doubly refractive or is an aggregate. Doubly refractive stones may be divided further as to weather they are uniaxial or bisexual. The Polariscope may also be used to detect pleochoroism in doubly refractive colored stones. Diamond cutters use the Polariscope to determine the strain characteristics of diamonds.
This instrument is pre-owned BUT in beautiful, like new condition!
