What the Bangkok Gem Fair Tells Us About the Future of the Trade

Every trade show is a snapshot, but the big ones are more than that. Walk the Bangkok Gems & Jewelry Fair with the right eyes and it becomes a forecast. The stones that fill the floor, the questions buyers ask, the technology in the machinery halls, the language on the booths, all of it tells you where this industry is heading long before the market reports catch up.

I have walked this fair for years, from inside a trade my family has been part of for over three decades, and this year the signals are unusually clear. The gem business is in the middle of a genuine structural shift, and if you buy, sell, or design with gemstones, the direction of travel matters to you. So instead of another visitor guide, let me offer something more useful: a read on the four forces reshaping this trade, what they mean for you, and where the smart money is already moving.

The Trade Is Growing, and Changing Shape

Start with the backdrop, because the scale of what is happening frames everything else.

The global gemstone market sits near 39 billion US dollars and is forecast to roughly double toward 73 billion over the next decade, growing at more than 6 percent a year. But the headline number hides the real story, which is not just growth but change in what people buy and how they buy it. Coloured stones are a leading driver, Asia is the fastest-moving region, and lab-grown material is carving out its own permanent place in the market. This is not a trade ticking along. It is a trade rearranging itself, and fairs like this one are where you see the rearrangement first.

Here are the four forces I would watch.

Force One: Verified Luxury Replaces Blind Trust

This is the deepest shift of all, and once you see it you cannot unsee it on the floor.

For most of this trade's history, value rested on reputation and a story. You trusted the dealer, you believed the origin, you took the grade on faith. That era is ending. Analysts now describe the market moving from opaque trading toward verified, traceable value chains, where origin proof and grading quality, not a good story, decide buyer confidence. Consumers are driving it, with surveys showing the overwhelming majority now expect transparency before they buy.

What does verified luxury look like in practice? A certificate you can check yourself, online, before you pay. Provenance recorded as data rather than described in words. Pricing you can see at the source instead of guessing at after several markups. This is exactly the standard we have built our business around, certified stones you verify yourself and factory pricing you can actually see, because I believed this shift was coming years ago. The buyers who win in the next five years will be the ones who demand proof as a baseline, and the sellers who win will be the ones who offer it without being asked.

Force Two: AI Steps Onto the Grading Bench

The machinery and technology on display at a fair like this always hints at the future, and this year the clearest signal is the arrival of artificial intelligence in the one place the trade guards most jealously: grading.

Major laboratories are now deploying AI to grade colour and clarity faster and more consistently than human graders can, and to pin down the origin of coloured stones with new precision. One respected lab launched an AI-assisted facility this year, others are using deep learning to identify and grade stones, and traceability platforms have already logged over a million diamonds. This matters because grading is trust, and AI is making trust faster, cheaper, and more consistent. For a buyer, it means the certificate in your hand is becoming more reliable than ever. For the trade, it means the days of fuzzy, subjective grading are numbered. I welcome it, because everything we sell is built to stand up to exactly this kind of scrutiny, which is why gemological institutes have come to our own office to study our material.

Force Three: Lab-Grown Becomes Its Own Tier, Not a Substitute

For years, lab-grown was framed as the cheaper alternative to mined. That framing is dead, and this fair makes it obvious.

Lab-grown diamonds are forecast to take more than a fifth of the diamond jewellery market by 2027, and analysts now describe them not as a substitute but as a distinct, permanent value tier with its own design language and its own customer. The same is happening in coloured stones. Lab-grown is no longer the understudy. It is a category in its own right, chosen on its own merits: consistent quality, open colour range, ethical production, and honest pricing.

This is the world we have lived in from day one. We do not sell lab-grown as a compromise. We sell it as the smarter choice for a specific, growing kind of buyer, and I explained why I made that bet personally in my story of choosing lab-grown over mined. The fair floor now agrees with a decision our family made years ago.

Force Four: Colour Takes Centre Stage

If diamonds defined the last era of jewellery, colour is defining the next one, and Asia is leading it.

Coloured gemstones are one of the strongest growth stories in the entire market, with buyers moving beyond colourless diamonds toward stones that express personality, meaning, and individuality. Younger buyers in particular want colour, and they want it in shades that mined material struggles to supply consistently or affordably. This is where lab-grown colour becomes genuinely powerful, because it can deliver any shade, matched and repeatable, at a price that lets a designer or a buyer actually commit to it.

It is also, frankly, where we have gone furthest. We grow a full spectrum of lab-grown corundum colours, from teal to marigold to plum, alongside fancy-coloured diamonds, precisely because we saw this colour wave building. A fair floor leaning harder into colour every year is not a surprise to us. It is the future we have been preparing for.

What This Means for You

Let me bring it down to earth, because trends only matter if they change what you do.

If you are a buyer, the message is simple: demand proof, embrace colour, and buy at the source. The trade is rewarding verification and transparency, so make them your minimum standard, and take advantage of a market where the colour you want is now growable and affordable.

If you are a designer or a brand, the opportunity is enormous. Consistent, certified, colour-matched lab-grown material lets you design with a freedom that was impossible a decade ago, and a direct relationship with a manufacturer at the origin protects your margin while these forces reshape the market. That is exactly what our wholesale and B2B sourcing is built for.

And if you are simply someone who loves stones, this is one of the best moments in the history of the trade to buy one. More proof, more colour, more honesty, and more value than ever before.

Where We Sit in All of This

I will end with a straight thought. Every one of these four forces, verified luxury, AI-backed trust, lab-grown as its own tier, and the rise of colour, points in the same direction, and it happens to be the direction our family pointed this business years ago. Certified stones you can verify. Colour grown to order. Honest pricing at the source. A category we believed in before it was obvious.

We did not follow these trends. We positioned for them, and the fair floor is now catching up to a bet we already made. If you want to work with a house that is already living in the future this trade is heading toward, that is exactly what we are here for.

Frequently Asked Questions

What are the biggest trends in the gem trade for 2026 and 2027? The leading trends are verified and traceable luxury, where buyers demand certification and provenance they can check; the adoption of AI in gemstone grading; lab-grown stones becoming a distinct, permanent category rather than a substitute; and the rising demand for coloured gemstones, led by Asia.

Is lab-grown becoming a permanent part of the market? Yes. Industry forecasts describe lab-grown as a structural shift rather than a fad, with lab-grown diamonds expected to take more than a fifth of the diamond jewellery market by 2027 and to form their own value tier with a distinct customer and design language.

What is verified luxury in gemstones? Verified luxury describes the market's move from trust based on reputation and stories toward value based on proof, including certificates buyers can verify online, traceable provenance data, and transparent pricing at the source. Origin proof and grading quality increasingly decide buyer confidence.

How is AI changing gemstone grading? Laboratories are adopting AI to grade colour and clarity faster and more consistently than manual grading, and to determine the origin of coloured stones more precisely. This is making certification more reliable and reducing subjectivity, which strengthens buyer trust across the trade.

Why are coloured gemstones growing so fast? Buyers, especially younger ones, increasingly want stones that express individuality and meaning beyond colourless diamonds. Coloured gemstones are a leading growth driver in the market, and lab-grown colour makes any shade available in consistent, affordable, matched quality, accelerating the trend.

How is Lab Grown Dreams positioned for these trends? Lab Grown Dreams built its model around certified stones buyers can verify, a full spectrum of grown-to-order colour including lab-grown corundum, and transparent factory-level pricing sourced directly in Bangkok, aligning with the shift toward verified luxury, lab-grown as its own tier, and the rise of colour.
