. . .
When was Matilde established and what inspired its creation?
Matilde Jewellery was established in December 2020. The inspiration for its creation stemmed from a desire to fill a gap in the market for luxurious yet sustainable and ethical fine jewellery. Witnessing the detrimental environmental impact of traditional jewellery practices, I was motivated to create a brand that prioritises sustainability, using lab-grown diamonds and 100% recycled 14k gold, ensuring that beauty and responsibility go hand in hand.
What is your brand ethos?
At Matilde Jewellery, our brand ethos is centred on sustainability, ethical practices, and enduring sophistication. We create fine jewellery using lab-grown diamonds and 100% recycled 14k gold, ensuring that every piece reflects our commitment to environmental responsibility and mindful consumption. Our designs fuse classic elegance with modern sensibility, celebrating the beauty of nature and the inherent grace of sustainable practices. Additionally, we prioritise wearability, crafting pieces that seamlessly integrate into everyday life, allowing our customers to effortlessly embody both style and sustainability. We strive to inspire a culture of appreciation for both craftsmanship and the planet.

What does luxury mean to Matilde?
Luxury means creating pieces that embody both exquisite craftsmanship and ethical integrity. It is about using lab-grown diamonds and 100% recycled 14k gold to craft designs that are not only beautiful but also responsible. Luxury, to us, is the fusion of timeless sophistication with modern sensibility, offering jewellery that is wearable, ethical, and cherished for generations. It represents a commitment to mindful consumption, celebrating the inherent beauty of nature and the grace of more sustainable practices.
For Matilde, how do the worlds of luxury and sustainability collide?
Both luxury and sustainability collide seamlessly in Matilde Jewellery. We believe true luxury is found in ethical integrity and environmental responsibility. By using lab-grown diamonds and 100% recycled 14k gold, we create exquisite pieces that are both beautiful and more sustainable. High-end craftsmanship with sustainable practices allows our customers to indulge in luxury while making a positive impact on our planet.

What shifts in the industry have you noticed in relation to sustainability? Is it enough?
In recent years, I have noticed a significant shift in the jewellery industry towards greater transparency and sustainability. More brands are adopting materials with smaller environmental impacts, such as lab-grown diamonds and recycled metals, and prioritising ethical sourcing practices. While these changes are encouraging and a step in the right direction, there’s still much to be done. True sustainability requires a widespread commitment to responsible practices and continuous innovation to reduce environmental impact. The industry must continue to evolve to meet these challenges fully.
How has working with Positive Luxury changed or informed your approach to sustainability?
Working with Positive Luxury has significantly enhanced our approach to sustainability at Matilde Jewellery. Their guidance and rigorous standards have helped us refine our practices, ensuring we meet high ethical and environmental benchmarks. This collaboration has informed our decision-making, from sourcing materials to production methods, reinforcing our commitment to responsible luxury. Positive Luxury’s framework has inspired us to continuously innovate and improve, ensuring our jewellery not only meets but exceeds expectations for sustainable and ethical craftsmanship.
What’s next for Matilde?
We are continuously focused on building and fostering our community. Expanding our selection of jewellery pieces, while steadfastly avoiding trends, ensuring each piece aligns with our core values of sustainability, transparency, and fairness. Our commitment lies in maintaining authenticity and quality, fostering a community that shares these values, and expanding our offerings in a thoughtful and purposeful manner.
