This webinar presents properties of the most common natural and synthetic red/pink gems using three portable in-expensive instruments:

  1. PL-Inspector/Jewellery Inspector – a mini UV lamp with magnifier to observe LW and SW fluorescence/phosphorescence of loose/mounted gems
  2. Portable polariscope – Cross polarised filters (CPF) to observe birefringence patterns.
  3. Spectroscope – a small portable instrument for observing a spectrum of a gem and identify impurities responsible for its color.

While many publications are available on inclusions and spectra of different gems there are no pictorial reference charts of fluorescence of gems and interpretations of reactions in relation to natural, treated or synthetic origins.

Outline of webinar (1h lecture):

Luminescence – principle and method of determining whether a gem is natural, synthetic or treated.

 Natural Diamond – contains impurities depending on growth environment that would cause different luminescence reactions

 Synthetic pink/purple diamond – strong orange fluorescence under LW/SW.

 Natural Rubies origins – Intensity of fluoresce in natural rubies could also give indication of magmatic or basaltic origin.

 Synthetic vs Natural Gems – manmade glasses, CZ, synthetic spinel and synthetic rubies and pink sapphires also have characteristic fluorescence under LW/SW light.

PRACTICAL WORKSHOP (30min): use of 10 pink/red gems and diamonds under “PL Inspector” and “Jewellery Inspector – portable, low-cost instrument allowing viewing of fluorescence and phosphorescence with a magnifier and app to capture and compare LW/SW reactions.
