Today, London-based fine jewelery brand Otiumberg will open its first standalone pop-up store in Marylebone, London, offering ear styling appointments and hosting piercing parties with nearby dermatologist practice Marylebone Skin. The three-week experiment marks a turning point for the 10-year-old brand, which has built a loyal following through approachable pricing and high-touch customer programs, including customer trunk displays.
Otiumberg was founded in 2016 by sisters Rosanna and Christie Wollenberg, who saw a gap in the market for affordable, high-quality, design-led jewelry. “We all have a lot of piercings but can’t find a brand that speaks to us. There’s just Tiffany or Topshop, no brand in between,” says creative director Christie Wollenberg at the brand’s hybrid office space in Holland Park (Rosanna had given birth the day before our interview). Otiumberg launched some cuddly hoops, and the brand grew organically through word of mouth. “We’ve always been customers, so our designs were very intuitive. Then we realized it wasn’t just for myself and my sister, there was a real demand for Otiumberg’s work.”

The brand has grown without outside investment, achieving 30% revenue growth by 2025. The sterling silver earrings are priced at $74, and the solid gold pavé diamond earrings are priced at $2,943. Bestsellers include Roscida Heart hoop earrings ($228 gold-plated), diamond initial tag pendants ($395), custom name pendants ($435) and a range of sculptural ear cuffs (prices ranging from $160 to $228).
The Marylebone pop-up, an extension of Otiumberg’s office space in the affluent Holland Park neighborhood of west London, has been a success: store sales were up 90% year-on-year in fiscal 2025, and the store accounts for 15% of the brand’s seven-figure annual revenue. (Wholesale accounts for 20%, and direct-to-consumer (DTC) accounts for the remaining 65%.)
Otiumberg celebrates its 10th anniversary this year and expects physical retail to drive its next phase of growth. “Marylebone is a jewel of retail. We think the other brands there create a beautiful adjacency,” said Otiumberg chief executive Áine McCourt. Nearby stores include Ganni, multi-brand beauty retailer Space NK and British lifestyle brand Toast.
The pop-up store is also the precursor to Otiumberg’s first flagship store, which will open this autumn on King’s Road, one of Chelsea’s most popular shopping streets. “We expect higher footfall [in Marylebone compared to Holland Park]so it will be a good training for our staff and give us a taste of what a flagship store will be like,” Wallenberg said. “Customer experience is very important to us – making sure customers feel they are getting a luxury experience regardless of price – so I think Marylebone is a training ground. “
