Trang Do on redefining modern heirlooms through meaningful luxury

In a fine-jewellery market often driven by trend cycles and visual excess, Trang Do has taken a markedly different path. As the founder and creative director of Kimjoux, she is building a contemporary jewellery house rooted in intention, emotional resonance and longevity, one that treats jewellery not as adornment, but as identity made tangible.

Trang’s relationship with jewellery began long before Kimjoux existed. Growing up, she observed how the women in her family valued their jewellery not for its material worth, but for the memories and milestones each piece carried. “Every piece represented a moment, a story,” she reflects. That emotional connection stayed with her as she later built a career in London working across brand and strategy roles. It was there that she noticed a gap in the market: jewellery that was aesthetically beautiful and well-marketed, yet rarely personal.

The defining moment came when Trang became a mother. Wanting to create something meaningful for her daughter, something she could one day inherit, crystallised her belief in jewellery as legacy rather than luxury alone. Kimjoux was born from that realisation, conceived as a fine-jewellery house where craftsmanship and meaning coexist, and where every piece begins with intention.

At its core, Kimjoux is guided by a clear mission: to create modern heirlooms that honour personal stories rather than fleeting trends. For Trang, luxury today must feel conscious, intimate and deeply connected to the wearer. “Every piece begins with a conversation,” she explains. That philosophy informs both the creative and commercial decisions behind the brand. Kimjoux is built on intention, craftsmanship and emotional resonance, ensuring each piece is not only beautifully made, but designed to endure emotionally and physically for generations.

What distinguishes Kimjoux in an increasingly crowded luxury landscape is its holistic approach. Responsibly sourced gemstones and specialist artisans form the technical foundation, but the true differentiator lies in the brand’s ability to translate emotion into form. Trang does not see luxury as excess. Instead, she defines it as authenticity. A Kimjoux piece, she believes, should make the wearer feel seen, a reflection of their identity, values and personal journey rather than a generic symbol of status.

This philosophy comes to life most clearly through Kimjoux’s bespoke and made-to-order work, which sits at the heart of the brand. Trang approaches each client relationship as a collaborative process, one that often becomes deeply emotional. Clients arrive with stories that may be fully formed or still unfolding, and her role is to help articulate those narratives through design, symbolism and material choice.

One such commission involved a client seeking to honour her late mother. Through conversations, shared memories and personal rituals, Trang incorporated a discreet motif inspired by the mother’s favourite flower, alongside a gemstone sourced from the region where she was born. When the client received the finished piece, the emotional response was immediate. “At that moment, it became more than jewellery,” Trang says. “It became a vessel of remembrance.” Experiences like this define Kimjoux’s purpose and reinforce its value beyond aesthetics.

Building a fine-jewellery house grounded in heritage, ethics and personal expression is not without its challenges. Ethical sourcing requires constant diligence, transparency and strong relationships with trusted partners. Scaling craftsmanship while maintaining consistency has also demanded careful balance, ensuring every piece receives the same level of attention regardless of demand. For Trang, growth without dilution is non-negotiable.

Looking ahead, her vision for Kimjoux is one of thoughtful expansion. Plans include deepening the bespoke offering, expanding internationally and eventually creating a physical space where clients can fully immerse themselves in the world of Kimjoux. Yet growth will never come at the expense of the brand’s soul. Conscious luxury, personal storytelling and exceptional craftsmanship will remain central as the business evolves.

Ultimately, Trang hopes Kimjoux will leave a lasting legacy — both for its clients and the wider jewellery industry. In an era defined by speed and disposability, she wants to champion a slower, more intentional approach to luxury. One where jewellery is designed to be inherited, not replaced, and where individuality and responsibility carry as much weight as design.

“If Kimjoux can inspire even a small shift towards more meaningful design and more conscious consumption,” she says, “then we will have created something that truly matters, something that lasts.”
