Jewellery Show London 2026 Exhibitors: What Buyers Can Source at Olympia

Diamond sourcing is a substantial part of the 2026 exhibitor mix. The live directory currently shows 52 listings categorised under natural diamonds and 35 under lab-grown diamonds.

For a retailer, however, the useful comparison is not simply natural versus lab-grown. Different diamond suppliers may suit very different buying models.

One retailer may need reliable access to classic round diamonds within a narrow commercial range. Another might be looking for elongated ovals, emerald cuts, matched pairs or stones for bridal manufacturing. A bespoke jeweller may care more about sourcing unusual specifications on demand than carrying deep inventory.

That means a useful supplier conversation should get beyond asking what diamonds are available today. Ask how the supplier handles:

• grading and certification;
• recurring requirements;
• less common shapes or specifications;
• matched stones;
• sourcing requests outside existing inventory;
• product information and documentation;
• lead times;
• ongoing availability.

A beautiful stone can make a good first impression. For a jewellery business, the more important question is whether the supplier can still help when your customer comes back six months later asking for something similar.

Uniglo Diamonds (Antwerp) is confirmed as a 2026 exhibitor at Stand B41.

The official Jewellery Show exhibitor profile lists Uniglo in Belgium and under natural diamonds. Its current profile also describes the company’s offering as including certified natural and lab-grown diamonds, together with diamond information, inventory browsing and purchasing guidance.

For buyers already planning to review diamond supply at the show, the most productive approach is to arrive with an actual requirement.

Rather than asking simply to “see some diamonds”, bring the specifications that matter to your business: preferred shapes, carat ranges, colour and clarity parameters, certification requirements, price positioning or the types of stones you repeatedly struggle to source. That gives both sides something concrete to discuss.

Diamonds are only one part of the loose-stone sourcing opportunity. The current exhibitor directory includes 26 listings in the loose gemstones category.

For retailers developing coloured-stone jewellery, bespoke businesses and designers, this part of the show can be particularly valuable because colour is difficult to judge from a supplier spreadsheet alone.

Seeing stones in person gives buyers the opportunity to assess characteristics that matter commercially as well as visually: colour consistency, matching, dimensions, suitability for existing designs and whether a supplier can reproduce a particular look when the first piece sells.

The official exhibitor product pages already show gemstone jewellery featuring stones such as sapphire, emerald, ruby and aquamarine, illustrating the breadth of coloured-stone product represented at the show.

If coloured gemstones form part of your buying plan, bring photographs or specifications of the designs they need to work with. It can make the conversation far more precise.

Fine jewellery is currently the largest product category in the online exhibitor directory, with 88 listings.

That matters because “fine jewellery” is not a single buying category.

Within one retail business it might mean diamond earrings that can be replenished throughout the year. Somewhere else it might mean higher-value occasion pieces, coloured gemstone jewellery, precious-metal collections or a small number of pieces intended to lift the overall positioning of the store.

Before comparing collections, decide what job the jewellery needs to perform:

• Are you filling an obvious hole in the assortment?
• Looking for a new price point?
• Trying to increase average transaction value?
• Replacing a supplier?
• Adding something customers cannot already find everywhere else?

Those questions give you a much better filter than simply deciding whether a collection looks attractive in a showcase.

The current Jewellery Show exhibitor directory contains 58 bridal jewellery listings, making bridal another substantial sourcing category for 2026.

Retail buyers should approach bridal differently from more trend-led collections.

A bridal piece may need to remain commercially relevant for years rather than months. Reordering matters. Matching wedding bands matter. Metal options matter. Ring sizing and manufacturing consistency matter.

If you are evaluating a new bridal supplier, useful questions include whether core designs remain available, how easily successful lines can be replenished, which customisation options are supported and how the supplier handles variations in stone specification.

The first order tells you whether you like the collection. The second and third orders often tell you whether the supplier relationship actually works.

Buyers looking beyond traditional fine and bridal categories have plenty to investigate as well. The live directory currently shows:

• 52 contemporary jewellery listings
• 58 design-led jewellery listings
• 48 silver jewellery listings
• 28 new designer listings

These categories can be particularly useful when a retailer wants to introduce something new without rebuilding the entire assortment.

A design-led collection might provide the recognisable piece that draws somebody towards a showcase. Silver may open a more accessible price point. Contemporary jewellery may help a retailer broaden its audience beyond traditional milestone purchases.

This is also an area where looking at products in person matters. Scale, weight, finishing, clasp quality and how a piece actually sits on the body do not always translate perfectly through ecommerce photography.

Not every worthwhile meeting needs to be with a supplier you already know.

The National Association of Jewellers reported in June that first-time exhibitors at the 2026 Jewellery Show include Anita Diamonds, Ward Gemstones, LU&ME, Hanron Jewellery and CaratIQ. The examples themselves show how broad the newcomer mix is, spanning diamonds, gemstones, jewellery and retail technology.

That is one reason not to schedule every minute of the two days. Appointments should protect the suppliers you definitely need to meet, but leaving some open time gives you a chance to find businesses that would never have appeared on your original shortlist.

Trade shows are easy to browse and surprisingly difficult to buy from well. The useful question is not how many stands you can visit, but how many buying decisions you can move forward.

The 2026 Jewellery Show is not limited to UK suppliers. The live directory currently contains exhibitors from markets including Belgium, India, Germany, the United States, South Africa, Hong Kong, Türkiye, Sri Lanka, Italy, Spain and others, alongside the large UK exhibitor base.

As of 19 August, the directory’s country filters show 143 UK listings, alongside 23 from India, 13 from South Africa, nine from the United States, eight from Belgium and five each from Germany and Türkiye, among other markets. Because the directory continues to be maintained ahead of the event, these figures should be treated as a current snapshot rather than a fixed final count.

For buyers, international representation can make the event useful for comparing sourcing models without arranging separate overseas buying trips for every initial supplier conversation.

The show is also promoting a dedicated India Pavilion, designed to connect trade buyers with Indian jewellery designers and manufacturers.

One of the easiest mistakes is to assume that every useful exhibitor will have jewellery in a display case.

The current directory includes 29 technology listings, 27 tools and equipment listings, 11 marketing-related listings and four store-design listings.

That opens up a different type of buying conversation. A jewellery business might attend primarily looking for stock and still discover that its bigger constraint is elsewhere: inventory management, point of sale, workshop equipment, customer communication, photography, store presentation or another operational process.

CaratIQ, for example, is one of the first-time exhibitors highlighted by the NAJ for 2026 and is described as a system developed for jewellery stores covering areas including point of sale, inventory, websites, marketing and CRM.

If you are bringing more than one person from your business, this is where splitting up can make sense. The buyer does not necessarily need to spend an hour evaluating retail software, and the person responsible for operations does not need to attend every gemstone meeting.

The exhibitor mix also extends beyond jewellery collections themselves.

The official directory currently includes categories for watches as well as tools and equipment, while individual exhibitor listings show businesses connected with CAD, casting, packaging, photography, polishing and other parts of the jewellery supply chain.

For an independent jeweller or growing retailer, these suppliers can be just as important as another finished collection.

A new product range creates revenue. A better process can improve the way every product is sold, serviced or replenished.

Treat the exhibitor list as a working buying document, not something to read from A to Z. Start with the problem you need to solve.

Then divide the exhibitors into three groups:

• Must meet — suppliers tied directly to an immediate buying requirement.
• Worth exploring — suppliers that could improve the assortment or solve a secondary problem.
• Discovery — exhibitors you leave intentionally unplanned.

The final group is important. If every appointment is decided before you arrive, you lose one of the main advantages of attending a physical trade show: finding something you did not already know to search for.

Try to compare more than product appearance.

For finished jewellery, ask about minimum orders, replenishment, manufacturing lead times, metal specifications, quality control, packaging and whether successful products can be reordered consistently.

For loose stones, concentrate on grading information, documentation, sourcing depth, consistency and how special requests are handled.

For newer brands, ask whether production capacity can keep pace if a collection sells better than expected.

And for every supplier, work out who you will actually deal with after the show. A friendly conversation on an exhibition stand is useful. Reliable communication six months later is more valuable.

A good buying day should leave you with more than photographs of attractive jewellery. You should be able to answer questions such as:

• Which suppliers deserve a second conversation?
• Which collections genuinely fill a gap?
• Which companies can support repeat business?
• Which products looked better in person than online?
• Which promising idea no longer makes commercial sense after seeing it?
• What did you discover that was not on the original buying brief?

Those notes are often more valuable than a bag full of catalogues.

With more than 200 exhibitors, the Jewellery Show offers enough choice to fill two days easily. The harder part is deciding where your time has the highest commercial value.

Start with the gaps in your own business.

If bridal is already strong, perhaps you do not need another hour looking at bridal. If customers keep requesting a diamond specification you struggle to find, that deserves attention. If your stock is good but your systems are slowing the business down, spend some of the day with technology suppliers.

A useful trade show is not measured by how many stands you visited. It is measured by what becomes clearer when you leave.

If natural or lab-grown diamonds are part of your 2026 sourcing requirements, meet Uniglo Diamonds (Antwerp) at Stand B41 and bring the specifications you want to discuss.
