Kimaï pitched in series 21 of Dragons' Den asking for £250,000 and got it, a rare full-price deal for one of the biggest cheques the show has ever handed out. Years on, if you are wondering whether the lab-grown diamond brand is still around, the short answer is yes. Kimaï is not just still trading, it has grown into one of the more recognised names in sustainable fine jewellery.

The short answer

Kimaï is still in business. The company remains active, keeps its own website running, and continues selling lab-grown diamond and recycled gold jewellery direct to customers. It does not sell through Amazon, its own storefront is the place to shop.

For a business that took a six-figure investment from a single Dragon, staying open and growing years later is exactly the outcome that deal was supposed to buy.

The Dragons' Den pitch

Kimaï appeared in series 21, episode 4, pitching in the Fashion & Beauty category. The founders, childhood friends Sidney Neuhaus and Jessica Warch, asked for £250,000 in exchange for 3 percent equity, implying a valuation of just over £8.3 million for a jewellery business built around lab-grown diamonds and recycled gold rather than mined stones.

That is a bold number to defend in front of five sceptical investors, and it is one of the largest single-Dragon deals in the show's recent history. The pitch landed.

The deal that got done

Steven Bartlett made the offer and put up the full £250,000 the founders asked for, taking the 3 percent equity on the table without renegotiating the split. No haggling over percentage points, no reduced cheque, just the number as pitched.

Bartlett has built his own reputation around consumer brands and digital-first businesses, and a direct-to-consumer jewellery label with a strong sustainability story and celebrity attention already attached fits squarely into the kind of pitch he has tended to back since joining the panel.

What happened after the cameras stopped

Kimaï had already built a following before its Den appearance, with endorsements and public wear from figures including Meghan Markle, Emma Watson and Jessica Alba, which likely made the pitch an easier sell than most. Company records show Kimaï Ltd as an active company, with regular filings and no signs of the kind of dormancy that usually precedes a quiet shutdown.

The brand has continued to position itself around lab-grown diamonds and recycled 18-karat gold, a category that has only grown more mainstream in the years since the pitch aired, which has worked in the company's favour rather than against it.

Where things stand now

Kimaï pitched in series 21 out of the UK, asked for £250,000 for 3 percent, and got exactly that from Steven Bartlett. Today the company is active, still selling, and still running its own website, with no Amazon storefront.

If you came here to check whether Kimaï survived its moment on television, it did, and by most public evidence it has done more than survive. It has kept growing in a jewellery category that gets more competitive every year.
