DIPLOMA PROGRAMME OVERVIEW
Sapphires. Rubies. Emeralds. And so many more. To capitalise on growing consumer interest in the coloured stone market, a solid foundation in the grading and identification of gemstones is absolutely essential. GIA's Graduate Colored Stones diploma programme will teach you how to "deal in colour" with the sharp insight of a true jewellery professional. In this acclaimed diploma programme, you learn how to make lucrative coloured stone sales presentations with confidence. And you develop the crucial skill of identifying the common and the more unusual gemstones found in today's marketplace. Moreover, by learning GIA's Colored Stone Grading System, you discover how to judge the quality of the stones you buy and sell. And that could make the difference between a poor business year – and a great one!
WHAT YOU LEARN
Learn how to distinguish between natural, treated, and synthetic gemstones and work with standard gemmological equipment. Then, train and practise grading colour, clarity, and cut, by applying GIA's Colored Stone Grading System. Discover which gems are most commercially important, and why. Then translate that information directly to your business. Acquire a comprehensive working knowledge of the Big Three: ruby, sapphire, and emerald. Plus, gain insight into how the constantly shifting trends in coloured stones supply affect gem prices – as well as your bottom line. And learn how to sell more coloured stone jewellery.
