What is the course about?
Why do these three gemstones have such importance in the jewellery trade? Rubies, Sapphires and Emeralds are the most commonly used gemstones in fine jewellery outside of diamonds. They have been revered and sought-after for thousands of years; the Ancient Greeks classified them as more rare and precious than diamonds. In recent years, there has actually been a swing away from the ‘usual’ white diamond, with young couples choosing to buy these rare coloured gemstones for their rings instead.
What will we cover?
The course will cover the history of each gem and the main sources, including mining and processing. Topics will include the geology and physical properties of these gemstones and how to assess them. You will also learn about gemstone cuts and the use of treatments. You will be taught how to use a loupe to assess the gemstones and learn about synthetics and imitations.
What will I achieve?
By the end of this course you should be able to...
- Use a loupe to assess gemstones

What level is the course and do I need any particular skills?
The course is at beginner’s level and no experience is necessary. It is ideal for people who have an interest in precious gemstones and jewellery set with precious stones. It would also be a good ‘refresher’ for people who work in the jewellery trade.
You should be able to follow simple written and verbal instructions to support demonstrations, handouts and for health and safety information, and be prepared to take part in group discussions.
How will I be taught, and will there be any work outside the class?
The course will be hands-on with many gemstone samples to view and detailed handouts to take away. There will be a short quiz to consolidate the information given out.
