Will I be assigned an instructor for the course?
The course is self-study. This means that all of the material is on our website, and the burden is on the student to follow the Syllabus to learn the material.
The benefit of this approach is that each student can learn at his or her own pace, and on his or her own schedule. Students can take as long as they want to complete each exam in the certification process to ensure familiarity and understanding of the material.
Won’t the self-study model be difficult if I’m a beginner?
For beginners we recommend following our structured Syllabus, however you may study the material in any order that suits you.
What is required to pass?
In order to pass the certification process the student must:
- Pass 1 100-question written exam with a score of 87% or better. The student may retake the exam an unlimited number of times until he or she passes.
- Thereafter, the student must also pass a practical exam which requires identifying 5 stones. We will mail?you the gemstones, which will be common to the trade and include natural, enhanced, synthetic, and assembled stones. Deductions will be made for errors, and the applicant must score 87% or better to pass.
- When the written and practical tests have been completed with passing scores, the IGS-Certified Diamond Specialist?certificate will be awarded.
How are the tests administered?
All examinations are administered via online test-taking software accessed via your password-protected account on the IGS website.
Can I see a sample of the test questions?
Sure! We have some?sample gemology questions from the actual IGS Professional Gemologist certification exam. This should give you a sense of the types of questions that we ask in our course exams. Questions cover gemstone formation, optical and physical properties, as well as faceting, grading, and appraising.
How long should it take me to complete the course?
The course is quite involved. This is not a casually created e-course, but rather a very comprehensive overview of some challenging material. Some members with previous gemology or geology experience may complete the course in as little as a few weeks, others may continue chipping away at it after two years. It really depends on your level of interest, motivation, and time commitment.
Can I get a refund if I am not satisfied?
You can get a full refund within 14 days of purchase as long as we have not mailed you the gem kit.
How does the IGS course compare with those offered by the GIA or similar organizations?
The GIA is an excellent organization. Their Graduate Gemologist degree is the most respected credential a person can hold in this industry. If you have the time and money, and are serious about a career in the gem industry, the GG course of study offered by the GIA should be your first choice.
The IGS certification courses were created for everyone else. The founder of IGS and original author of the Professional Gemologist program, Donald Clark, has strong connections with the lapidary community. For years, he listened to amateurs giving inaccurate advice to others. For example, he heard things like: “If your blue stone has an RI of 1.625, then it is topaz, not aquamarine.” Those two properties, color and RI, also belong to tourmaline and a few rare minerals. Blue topaz and blue tourmaline have vastly different values. Not knowing the difference can be costly, in terms of both money and reputation.
Donald Clark believed that the problem stemmed not from the well-meaning lapidary sharing his incomplete knowledge, but rather that there wasn’t anywhere to learn gem identification, short of taking (what was back then) a $3,000 course. For them, he created IGS. It is dedicated to all the gem cutters, collectors, jewelers, and others wanting to know more about gems. The Professional Gemologist program was also created for those lacking the resources for a GG degree. A typical example would be a person making a midlife career change. This often involves working two jobs for a period, or the time consuming process of starting a new business.
What the IGS certification tells a customer, or potential employer, is that the holder has proven their knowledge of gemology: that they are well versed in its terminology, the properties of various gemstones, how they are valued, and that they possess the skills and knowledge to distinguish one gem from another. But let us be clear: having? a certification from IGS may open doors to a career in gemology. But it is the way an individual presents themselves and his or her actual experience and work ethic that determines success.
