We offer short, practical gem courses, seminars and gemmological services. Our courses are short (one to three days) and inexpensive. You will NOT need to learn scientific and mathematical concepts on our courses: we emphasis the rarity, quality and beauty of gems. Gem knowledge with us is fun and informative!
