Add an optical observation to gemstone testing

A gemstone's behaviour under polarised light can provide useful information alongside other tests. The conoscope is used with the polariscope to inspect an interference figure under the appropriate conditions.

The stone's transparency, orientation and cut affect what can be observed. Use the result with other gemmological evidence rather than treating one pattern as a complete identification or proof of a stone's origin.
