Gem and Jewellery Trade Secrets


       Discover your jewellery!

Start your journey at the source of gemmology: learn about gemstone origins, how gems are mined and who the middle-persons involved are that craft and carry these extraordinarily valuable minerals to market. Learn about gemology quality and value factors for all types of gems, from Diamonds to Coloured Stones, Organics to Jade. This comprehensive course gives you the knowledge and power to take control of your gem purchases (if you are a collector or enthusiast) or your sales process (if you are a designer or jewellery professional). Beyond the common trade practices and pricing, you will learn about imitations, synthetics and treatments sometimes used to enhance or even to deceive. Gemmology is a great chance for personal development.

You will never look at gemstones in the same way again!
