De Beers Group to shut LGD jewellery brand Lightbox, will focus on naturals
The move underscores De Beers Group’s commitment to natural diamonds
De Beers Group today announces its intention to close its lab-grown diamond (“LGD”) jewellery brand, Lightbox, reinforcing De Beers Group’s commitment to natural diamonds in the jewellery sector. As part of the closure process, De Beers Group is discussing the sale of certain assets, including inventory, with potential buyers.
Lightbox, which was established in 2018, has highlighted that LGDs are a distinct product from natural diamonds, with different attributes and different value. The business was launched with transparent linear pricing of $800 per carat. Since then, LGD prices in the jewellery sector have fallen 90% at wholesale, tracking closer to a cost-plus model as they have diverged from natural diamond prices. Reflecting this sharp price decline, De Beers Group intends to discontinue the Lightbox business. The evolution of LGD values in the jewellery sector underpins De Beers Group’s core belief in rare, high-value, natural diamond jewellery as a separate category from low-cost, mass-produced LGD jewellery.

The proposed closure of the Lightbox business reflects a key executional milestone in De Beers Group’s Origins Strategy, as set out in May 2024, to focus on high-return activities and streamline the business. The closure will enable De Beers Group to reallocate investment to initiatives focused on reinvigorating desire for natural diamonds through category marketing.
De Beers Group will work closely with employees, retail partners, suppliers, and other stakeholders to ensure a smooth process over the coming months. Customers will continue to receive support for existing purchases, including warranties and after-sales services, during the closure process.
Element Six, De Beers Group’s subsidiary that previously produced lab grown stones for Lightbox, maintains its exclusive focus on industrial solutions using synthetic diamonds. Building on its world-leading status developed over more than seven decades, Element Six is well-positioned to seize the rapidly growing potential for synthetic diamond applications across a range of future-facing technologies and applications.

Al Cook, Chief Executive Officer of De Beers Group, said: “As we move towards becoming a standalone company, we continue to optimise our business, reduce costs and build a focused De Beers that is positioned for profitable growth.
“The persistently declining value of lab-grown diamonds in jewellery underscores the growing differentiation between these factory-made products and natural diamonds. Lightbox has helped to highlight the fundamental differences in value between these two categories. Global competition continues to intensify with more low-cost lab-grown diamond production from China. In the US, supermarkets are driving down lab-grown diamond jewellery prices. Overall, we expect both the cost and price of lab-grown diamonds to fall further in the jewellery sector.
“The planned closure of Lightbox reflects our commitment to natural diamonds. We are also excited at the growing commercial potential for synthetic diamonds in the technology and industrial space.”

The Woman Wearing The Diamond Was Never The One The Ad Was Talking To
Disha Shah, Founder & Designer, DiAi Designs Says That The Brands That Shift From “She Deserves It” to “She Chose It” Won’t Just Win Cultural Relevance – They’ll Own The Future Of Jewellery Marketing.
Indian jewellery advertising has always centred the woman. She has been the face of every campaign, draped in gold, luminous at the occasion, receiving the gift with practised grace. What she rarely was, until recently, was the intended audience.
The creative language of the category was built around a genuine economic reality. For decades, the buyer in Indian fine jewellery was the patriarch, the husband, the father, the family elder making a financial decision on behalf of a woman whose purchasing autonomy was limited. Advertising followed the money. The gift reveal, the bridal close-up, the family approval shot: these were not arbitrary creative choices. They reflected who held the purse strings, and they became so embedded in the category’s visual grammar that they outlasted the conditions that created them by an entire generation.
That structural reality has now reversed. Jewellery purchases now extend beyond weddings and festivals to daily wear, driven by financially independent working women. The self-purchasing woman is no longer an emerging segment; she is the category’s fastest-growing buyer, approaching the decision differently from the buyer the industry originally designed itself around. She is not waiting for an occasion. She is not waiting for someone to present a box. She researched the piece, chose it, and bought it because she wanted it.
The advertising, for the most part, has not caught up.
Some brands are beginning to recognise this. CaratLane’s #WearYourWins movement and Tanishq’s sustained push toward the “woman as decision-maker” are meaningful steps. But what makes these campaigns commercially smart is not just cultural alignment. Research from Harvard Business School finds that women systematically provide less favourable assessments of their own performance and potential than equally performing men. This documented self-promotion gap persists even when women know they have outperformed others. Campaigns that actively celebrate female self-recognition are not just filling a creative gap. They are responding to a behavioural reality that has gone largely unaddressed in the category. The brands doing this well are not being progressive for their own sake. They are being accurate about who their buyer is and what she needs to hear.
Look at the Women’s Day 2026 campaigns across the industry. The conversation is clearly starting to pivot. Brands are finally stepping away from the usual gifting tropes and reframing jewellery as a tool for personal milestones and self-expression. But these remain exceptions. The dominant campaign language of Indian jewellery- the gesture, the reveal, the woman being seen rather than deciding- has not structurally changed.
The media mix tells the same story. Titan leaned heavily on television in FY25, with ad volume surging to 77% of its mix, a broadcast medium built for household reach rather than the individual, financially independent woman who now represents the category’s fastest-growing buyer.
Meanwhile, digitally native BlueStone achieved 50% of online jewellery ad volumes on a budget nearly ten times smaller than Titan’s. The channel that reaches the self-purchasing woman directly is delivering outsized results on a fraction of the spend. The implication for where the industry should be directing its creative attention is fairly clear.
Consider what a brief genuinely written for this buyer would look like. No occasion in the shot. No second person in the frame presents anything. The opening line is not “for the woman who deserves to be celebrated.” It is “she saw it, she wanted it, she bought it.” The product earns its place not through sentiment but through desire. The copy does not explain why she is worth it. It assumes she already knows. That is not a tonal adjustment. It is a fundamentally different creative architecture, and very few briefs in this category have been written that way.
The LGD category has a specific opportunity here that established houses do not. Without decades of legacy campaign language to protect, an independent designer in this space can build advertising from a blank page, one written entirely around the woman who is actually making the purchase. The brief does not have to accommodate inherited assumptions about who the buyer is or what she is waiting for. That is not a small advantage. In a category where the dominant creative language was built around a buyer who is no longer the one making the decision, starting without that inheritance may be the most powerful creative position available.
The woman wearing the diamond has always been visible. What is changing now is who gets to decide. The brands that build their creative around that reality will not just be more culturally relevant. They will be better positioned for every year that follows. The advertising has not caught up yet. But the buyer already has.
