Opal and Tourmaline day

opal and tourmaline

Opals and tourmaline...

A one-day course introducing two stunning species of gemstones – opals and tourmalines.  This day is all about colour!

We will look at the various different varieties of opal and explore the colours of tourmaline, how both gems formed, their characteristics and how testing can help identify them, their optical phenomena, treatments and both synthetic and imitation stones.

You will be taught how to use a 10x loupe to look at both internal and external features of gemstones and have the opportunity to look at a variety of opal and tourmaline gems which demonstrate examples of some of the subjects we will discuss.

How to use some of the testing equipment used by gemmologists will be demonstrated and then you will have the opportunity to try them for yourself to see in practise some of the theory discussed during the day.

Are you

  • a gem lover
  • a jeweller who wants to know a bit more about the stones you are using in your work
  • an antique dealer who would like to understand more about the stones you are seeing

why not spend a day with me learning a little about the tests gemmologists use to help identify gemstones, the science behind these tests and their results and have the opportunity to handle the stones and see this for yourself.

The day will be suitable for those who have completed my Introduction to Gemmology day or those who are approaching the subject for the first time and will be a mixture of theory and practical work.
