Colour can give you a clue. Appearance can give you an impression. But neither can give you a definitive identification.

Professional gemstone identification involves understanding the properties of a stone, knowing which tests to perform and being able to interpret what your equipment is telling you.

That distinction matters when you’re buying, selling or advising customers about coloured gemstones.

The Basic Gemstone Identification Course at the Academy of Gemmology introduces the practical skills and equipment used to distinguish natural gemstones from synthetics and imitations.

The course also includes the Coloured Gemstone Grading System and Pricing Course, giving you a broader understanding of both identification and the commercial side of coloured stones.

Learn to investigate the stone, not just look at it.

Before a diamond is polished, there are questions to answer.

💎 What does the crystal morphology reveal?
💎 What internal characteristics are present?
💎 How much weight could potentially be recovered?
💎 And what might that mean for the finished stone and its value?

Understanding rough diamonds requires more than knowing what a polished diamond looks like.

The Rough Diamond Grading Course at the Academy of Gemmology explores the practical principles behind rough diamond assessment, including crystal morphology, sorting mechanics, weight estimation, interior flaw tracking, potential yield and financial value.

The better you understand the rough, the better you understand its potential.

It’s a simple question.

But if the answer is no, it can introduce an unexpected delay into a sale.

The customer is interested. Your sales team is ready. Then the gemstone needs to be sent away for identification before the customer is comfortable proceeding.

There is another option.

The Gem Lab’s Point-of-Sale Verification service allows straightforward coloured gemstone identifications to be completed before the stone reaches the sales counter.

At R275 + VAT per stone, each verification includes a unique reference number and QR code, allowing the identification to be checked online.

So when your customer asks:

“Has this stone been independently verified?”

Your sales team can answer:

“Yes.”

No frantic phone call. No unnecessary delay. Just independent verification ready when your customer needs it.

INTERESTED IN GEMSTONES? LEARN TO LOOK BEYOND THE SPARKLE. 💎

A gemstone’s colour and appearance can tell you a lot, but knowing how to identify what you’re actually looking at takes a different set of skills.

From understanding gem properties to distinguishing genuine gemstones from synthetics and common imitations, gemmology gives you the knowledge to make more informed decisions.

The Academy of Gemmology’s Basic Gemstone Identification and Coloured Stone Grading Course combines theoretical knowledge with hands-on practical training, guided by an experienced gemmologist.

A professional jewellery valuation isn’t simply about deciding what a piece is worth.

The figure needs to be supported by a clear assessment of the jewellery itself and a sound understanding of the methodology behind the valuation.

Gemstones. Precious metals. Mount styles. Hallmarks. Provenance. Market conditions. The purpose of the valuation.

All of these factors can influence the conclusion.

The Jewellery Valuation Course at the Academy of Gemmology develops the practical knowledge and methodology needed to approach professional valuations with greater confidence and consistency.

Whether the valuation is for insurance, an estate, retail resale or professional appraisal, the reasoning behind the number matters.

Your valuation is only as strong as the knowledge behind it.

Imagine a customer is interested in a valuable coloured gemstone.

They ask whether the stone has been independently identified.

You could say:

“We’ll have to send it away and get it checked.”

Or you could say:

“Yes, it has already been independently verified by The Gem Lab.”

The Gem Lab’s Point-of-Sale Verification service is designed to make independent identification part of your process, rather than something you arrange at the last minute.

For R275 + VAT per stone, straightforward gemstone identifications receive a unique reference number and QR code, allowing the information to be verified online.

For jewellers, it’s a small step that can make the sales process simpler. For customers, it provides an additional layer of confidence in what they’re buying.

Don’t wait until your customer asks for verification. Have your important stones checked before they reach the counter.

A professional diamond assessment is about more than looking at a stone and deciding whether it appears good.

You need to know what to look for, which characteristics matter, how to assess them consistently, and how to interpret what you’re seeing.

From the 4Cs to laboratory-grown diamonds and commercial grading reports, diamond grading requires both knowledge and practical experience.

The Practical Diamond Grading Course at the Academy of Gemmology is designed to develop those skills through hands-on training in professional laboratory conditions.

Because knowing what to look for changes what you see.

Not every gemstone is exactly what it appears to be.

Natural gemstones can be treated, while synthetic and imitation materials can closely resemble their natural counterparts. Without the right knowledge and testing techniques, the difference isn’t always obvious.

The Basic Gemstone Identification Course gives you the practical foundation to examine coloured gemstones using essential gemmological equipment and identification techniques.

Know what you’re looking at before you put a value on it, sell it or stand behind it.

A rough diamond doesn’t reveal its full potential at first glance.

Its crystal shape, weight, internal characteristics and potential yield all contribute to the decisions made before it ever becomes a polished stone.

The Rough Diamond Grading Course introduces the skills and knowledge needed to assess rough diamonds and understand the factors that influence their potential.

Learn to look at the rough, and see what could be.
