Gübelin Coloured Gem Professional - The Basics introduces you to the emotional, historical and gemmological basics of the “Big Three”: emerald, ruby and sapphire. Listen to their stories and learn about the history of these important gemstones. Learn about their key gemmological characteristics, and understand their main valuation criteria. An invaluable introduction to anyone interested in or wishing to expand their knowledge about coloured gemstones.
Our online program is divided into four different modules: “The Basics: Scratching the Surface”, “The Basics: Emerald”, “The Basics: Ruby” and “The Basics: Sapphire” which you can enroll separately by module. Built as a self-paced learning platform, our online courses give you the liberty to attend the course whenever you want and follow it at your own pace.
Each module is specially designed to provide you with a unique learning experience during which you will gain a strong foundation of the topics covered. At the end of each module, a short test will validate your course (75% passing requirement), upon which, if successfully completed, you will receive a certificate in PDF format.
After successful completion of all four modules, you will receive your hard-copy “Coloured Gem Professional - The Basics” certificate. You are then entitled to sign up for the subsequent level: Gübelin Coloured Gem Professional - Level 2, which is the next step up in exploring emeralds, rubies and sapphires. The completion of Level 2 will entitle you to proceed with Gübelin Coloured Gem Professional - Level 3, the practical culmination of the Coloured Gem Professional. To attend these two courses, students will need to attend the physical classes at one of our campuses. Please visit our upcoming course schedule on our website for available class dates at our campuses in Switzerland, Hong Kong and China.
