Certificate Courses
01
Introduction to the Diamond Industry
2 Weeks
The diamond industry can be overwhelming for newcomers because it involves highly specialized terminology, complex supply chains, and strict global standards. This course helps you build a strong foundation, so you do not feel lost when you move into technical training or a professional role. You will understand how rough becomes polished, how the market works, how diamonds are priced, and what ethical issues shape today’s industry. If you want to enter the industry confidently and avoid costly misunderstandings later, this course ensures you start with the right knowledge base.
02
Foundations of Diamond Sorting and Grading
2 Weeks
Diamond sorting and grading are core skills across the entire value chain. Whether you plan to work in manufacturing, retail, buying, or valuation, you must understand how quality is determined. This course gives you hands-on exposure to real diamonds, allowing you to learn how professionals judge clarity, color, cut, weight, shape, and inclusions. By gaining these skills early, you reduce the risk of costly mistakes, build credibility, and set yourself up for advanced roles where precision and trustworthiness are essential.
03
Diamond Polishing – Brillianteering
2 Weeks
Brillianteering transforms a diamond from a rough geometric shape into a sparkling finished gem. This advanced stage requires exceptional control, symmetry, and attention to detail. The course helps you refine your technique so you can produce diamonds that meet international quality standards, making you highly employable.
If you want to polish high-value stones, work in premium cutting centers, or build a long-term artisanal skill set, this course elevates you from a basic polisher to a finishing specialist.
04
Diamond Polishing –
Blocking
6 Weeks
Blocking creates the basic structure of a diamond, and it is one of the most technical and respected skills in manufacturing. A diamond’s brilliance starts with how well it is blocked. This course allows you to develop patience, precision, and machine-handling skills under expert supervision.
If you aim to build a solid polishing career, blocking is where you prove your potential. A strong blocker becomes a valuable asset in any polishing factory and can earn competitive wages due to the high level of skill involved.
05
Professional Diamond Marketing and Pre-Cutting Techniques
2 Weeks
Before a diamond is cut, someone must decide the most profitable way to shape it. Poor decisions at this stage can destroy value or reduce yield dramatically. This course trains you to plan rough stones like a professional — identifying flaws, analyzing potential shapes, and marking stones for optimal results.
06
Lab-Grown Diamond Identification
1 Day
The rise of lab-grown diamonds has created new challenges for buyers, sellers, jewelers, and appraisers. Without proper training, it’s easy to confuse natural and lab-grown stones, leading to financial losses and reputational damage.
This short course gives you practical skills to confidently identify lab-grown diamonds and understand when advanced testing is required. Whether you deal with customers or trade stones, this knowledge protects your business and helps you maintain transparency and trust.
07
Diamond Industry Foundation & Value Chain Awareness
1 day
Many people working in the industry only understand their department, not the full value chain. This lack of big-picture knowledge can limit career growth and cause communication problems within companies.
This course gives you an insider’s view of every stage: mining, sorting, cutting, trading, certification, and retail. It is ideal for building confidence, improving job performance, and helping you understand where your role fits in the bigger ecosystem. It’s also excellent for team alignment and new staff onboarding.
08
Rough Diamond Evaluation and Buying Skills
2 Days
Evaluating rough diamonds is one of the most profitable yet risky areas in the industry. A buyer must judge what a rough stone will yield — without seeing inside it. This course helps you minimize risk by teaching you how to assess quality, calculate potential yield, and estimate costs versus profits.
If you plan to buy rough stones, participate in tenders, or operate in the mining or trading sector, this training is essential to avoid losses and negotiate effectively. These skills are also valuable for anyone wanting to start a small diamond-buying business.
