      • Gem and Jewellery Appraisal CourseThe Montreal School of Gemmology’s Gem and Jewellery Appraisal program is recognized by the Canadian Jeweller’s Association. Dedicated exclusively to evaluation techniques pertaining to gems and jewellery, our course focuses on practical work with our vast collection of coloured gems, diamonds, pearls, and jewellery to prepare students for the tasks and challenges they will encounter as appraisers. Organized visits to local jewellery manufacturers, practicing appraisers, computer assisted design workshops, and others along with lectures from respected industry professionals and experts allow students to start building their own network of professional contacts
      • Rough Diamond Grading and Evaluation DiplomaThe Montreal School of Gemmology is one of the few institutions to offer intensive and comprehensive training in rough diamond grading and evaluation. Our structured program uses a series of presentations and an emphasis on practical work to help students master the following concepts: How to assess the quality and value characteristics of rough diamonds How to sort and select quality rough How to calculate and evaluate a rough diamond’s potential yield How to differentiate between natural diamond and it’s many imitations Our well-equipped laboratory classroom and large collection of rough diamonds allows students to apply their new skills with the guidance of our experienced and professional instructors.

      • Basic GemmologyThe Basic Gemmology course is largely devoted to the various instruments used to identify gemstones, as well as their principles of operation. Many topics are covered in this course: the chemistry of gemstones, their physical and optical properties as well as notions of crystallography, light absorption, spectroscope, refraction and reflection, refractometer, optical character and sign, dispersion, reflectometer, polarized light, polariscope, pleochroism, dichroscope, colour filters, density, luminescence, thermal conductivity, and finally the microscope and loupe. A great introduction to the world of gemmology!
      • Advanced GemmologyThe Advanced Gemmology course is largely devoted to the imitations of gemstones, the different methods of manufacturing synthetic gems – as well as techniques to distinguish them from their natural counterparts – and the detection of the different treatments used to improve the appearance and/or value of gemstones. Many topics are covered in this course: artificial gems and composites, methods used to manufacture synthetic gems including Verneuil, Czochralski, melting, hydrothermal, copper skull, zone fusion, horizontally oriented crystallization, HPHT, CVD, detonation, sublimation and modified Stöber, and the different characteristics to identify them. Treatments and techniques for improving gemstones will also be discussed, including heat treatment, surface and volume diffusion, lead glass fracture filling, filling of fractures with cobalt-doped lead glass (for sapphires), flux crack healing, methods of improving the purity of diamonds, HPHT treatment of diamonds, quench-crackling, surface modification, laser drilling, irradiation and scientific gem identification techniques.
      • Gem IdentificationIn contrast to other programs, this course takes a concrete approach to the methods of identifying gems by first grouping them by colour and transparency. Each gem of the same colour group is characterized according to its refractive index, depending on whether or not it can be measured with a refractometer (maximum 1.80), then according to its unirrefractive or birefringent character, as well as uniaxial, biaxial or non-crystalline. Finally it is determined whether the gem has an optical phenomenon or a specific appearance. Many topics are covered in this course, including an introduction to gem identification and the tests that are commonly used to identify gems. An in-depth look is taken at each of the ten colour groups (colourless or white, red, pink, orange, yellow, blue, green, violet or purple, brown, black or grey) as well as phenomenon or unusual looking gems. What are the important varieties and species of gems that are commonly found in each colour group? How can we distinguish between gems that are generally confused with each other (aquamarine and blue topaz, emerald and chromal tourmaline, diamond and laboratory-created moissanite) or that have similar physical and optical properties (amethyst and violet scapolite)? Study of all laboratory-created,…

      • Certificate in GemmologyCurious and passionate about gemstones? Whether you are new to the fascinating world of gems, or already involved in the gem and jewellery industry the EGM Certificate in Gemmology program allows you to pursue your passion at your own pace in a structured yet open format leading to a gemmological credential. To obtain the EGM Certificate students must complete the following core courses: Gemmology 1, 2, 3, and 4 EGM’s Diamond Grading Workshop Students in the program can participate in one or two courses per semester.
      • Gemmology 1Unearth the fascinating world of gems and see why these beautiful stones have captured our imagination for thousands of years. In a relaxed and friendly environment you will discover gems you have never heard of and learn the important characteristics of well-known gems.
      • Gemmology 2Continue to discover new gems and learn how to accurately identify them with instruments and testing methods used by gemmologists. Building on the course material seen in Gemmology 1 students learn systematic testing and observation techniques used by professionals.
      • Gemmology 3How do the professionals approach gem identification when faced with similar looking stones? Having discovered the astonishing array of beautiful gems in Gemmology 1 and learning how to systematically test and analyze these gems in Gemmology 2 students now hone their gem identification skills by differentiating and identifying potentially similar looking gems.

      • Diamond Grading WorkshopDiamonds have long been thought of as symbols of strength, prestige, and eternal love however, not all diamonds are created equal. Learn what factors determine the quality and value of nature’s most sought after gemstone. This two-day practical workshop takes participants through the grading process used by gemmologists, jewellers and laboratories.
      • Coloured Stone Grading WorkshopColoured gemstones are more popular than ever and it is important that gem dealers, appraisers, and jewellers understand the criteria used to determine the quality and value of coloured gemstones. During this two-day practical workshop participants will learn how to assess the quality of different coloured gemstones based on: colour, cut quality, and clarity factors. Understanding the impact these criteria have on the value of coloured gems is essential for anyone involved in the gem and jewellery industry.
      • Pearl Grading WorkshopPearls have a timeless and universal appeal however the pearl industry has changed dramatically in the last 40 years with the introduction of many new varieties of cultured pearls. Knowing how to distinguish the different varieties and grade pearls based on the appropriate quality and value criteria is essential for jewellers, gemmologists, appraisers, and pearl aficionados. Starting with an overview of pearl history and production then focusing on hands-on exercises, this two-day workshop follows the pearl from nucleation to necklace.

      • Opal Grading WorkshopOpal’s unparalleled beauty lies in its almost magical play of colour. Opals have long been valued for their rare ability to capture the rainbow. In the first century A.D. Pliny the Elder wrote of opals: “For there is amongst them the gentler fire of the ruby, the rich purple of the amethyst, the sea-green of the emerald, and all shining together in an indescribable union.” Greg Kratch, a gemmologist and lapidary whose passion for opals is both unrivaled and contagious, developed this workshop for the Montreal School of Gemmology (EGM). Greg spent over ten years mining, cutting, and grading opals in Australia’s famed opal region of lightning ridge and has studied and worked extensively with opals from the new Ethiopian deposits.
