Copenhagen-based jeweler Maya Bjørnsten has spent the last 17 years building a brand around a single idea: raw diamonds, uncut and unpolished, exactly as they come from the earth.
The quiet rebellion of rough diamonds
RoughDiamonds.dk, founded in 2007, uses only natural, unprocessed diamonds. While most jewelers mix rough and polished stones, Bjørnsten remains a purist. Each piece is unique, shaped by the diamond’s natural form rather than human alteration.
Her approach comes from personal beliefs shaped by her upbringing. Growing up in a Danish hippie commune, she recalls a childhood without clear rules. That outlook influences her work, where imperfection isn’t just tolerated but valued.
Bjørnsten didn’t start in jewelry. Before launching her brand, she worked in film production and advertising. The shift began when her former brother-in-law showed her photos from a diamond-sourcing trip to Antwerp for his traditional jewellery house. Bjørnsten explains: “Traditional jewellery never spoke to my heart or suited my personality; it felt too rigid and uniform. The turning point came when I held my first rough diamond. I was struck by its quiet power and ancient energy. It didn’t need human intervention to be magnificent. I wanted to create a brand that lets people wear a piece of eternity.”

She was amazed to see what polished diamonds look like before being “perfected” by man. She realised that with raw diamonds, she could adopt imperfection and create jewellery differently. The result is jewels with a soft glow, aligning with Scandinavian sensitivity toward quiet luxury.
Bjørnsten says: “Jewellery has returned to its ancient roots—acting as an amulet, a talisman, a deeply personal symbol, or a marker of an important life milestone.”
From selection to setting: a slow, deliberate process
Key to the ethos of Rough Diamonds, founder Maya Bjørnsten carefully selects every single diamond herself, analysing each for its beauty and personality. Fundamental to Bjørnsten’s process is that she selects each and every stone herself, slowly and patiently poring over parcels of rough, treating each as an individual. This hands-on method works because of long-standing, trusting relationships with diamond dealers in Antwerp who give her first dibs on parcels.
Those connections also ensure traceability. Unlike polished diamonds, which often lose their origin in global supply chains, she knows the origin of each stone before it becomes an anonymous cut-and-polished commodity. The brand uses only recycled gold and sources from RJC-approved suppliers, strengthening its ethical reputation.

Bjørnsten is drawn to imperfections, especially inclusions visible to the naked eye. She has found inclusions resembling foam, a diamond within a diamond, and even one that looked like a Christmas tree. “I’m not seeking standard calibration, but distinct personalities, unique crystal habits, fascinating textures, the way a stone catches the light, and, of course, the breathtaking natural colours only the Earth can produce,” she says.
Once selected, each stone presents a new challenge to the three diamond-setters and goldsmiths in the Copenhagen atelier. Each mount is hand-sculpted in recycled gold to fit its unique contours, ensuring no two are ever the same. The team’s experience allows them to work with the unpredictable nature of rough diamonds.
Rough diamonds come in a variety of shapes and colours, and no two are ever the same, meaning each jewel is one-of-a-kind. The brand’s Copenhagen boutique, hidden in a quiet courtyard, also serves as an atelier where customers can watch their pieces being made. For those who can’t visit, the website offers ready-to-wear items and custom commissions.
Her work has changed perceptions of fine jewelry. By rejecting the industry’s focus on flawless symmetry, she created a brand that feels both timeless and contemporary—a reminder that beauty often lies in what remains untouched.
