The big three - ruby, emerald and sapphire!

This informative practical day will cover all aspects of these beautiful gems. You will begin by looking at their properties and learn how to identify natural ruby, emerald and sapphire, followed by their treatments (including lead-glass filling of ruby), simulants and synthetics. Through hands-on observation and learned gem-testing techniques, you will handle and examine a wide range of these stones, gaining experience and knowledge about ‘quality’ and ‘value’ and how they affect current market values of stones.

Who should attend?

A great workshop for anyone already working in the gem trade looking to expand on existing knowledge.

Qualifications required:

Please note: to attend this workshop you will need an intermediate level of gemmological knowledge, either from a qualification such as Gem-A's Foundation or Diploma in Gemmology, or practical experience gained through employment within the trade.
