Today, London-based premium jewelry brand Otiumberg is opening its first standalone pop-up in Marylebone, London, where it will offer ear-styling appointments and host a piercing party with nearby dermatologist clinic Marylebone Skin. The three-week experiment marks a turning point for the 10-year-old brand, which has built a loyal following through accessible prices and high-touch customer initiatives, including client trunk shows.
Otiumberg was founded in 2016 by sisters Rosanna and Christie Wollenberg, who saw a gap in the market for design-led jewelry that is both affordable and high quality. “We both had loads of piercings, but couldn’t find a brand that spoke to us. There was Tiffany or Topshop, and nothing in between,” says creative director Christie Wollenberg at the brand’s hybrid office-store space in Holland Park (Rosanna had given birth the day before our interview). Otiumberg launched with some huggie hoops, and the brand grew organically through word-of-mouth. “We’ve always been the customer, so our design is very intuitive. And then we realized it wasn’t just for myself and my sister, there was a real demand for Otiumberg’s pieces.”

The brand has grown without external investment, achieving 30% revenue growth in 2025. Prices start at $74 for sterling silver earrings and reach $2,943 for solid gold pavé diamond earrings. Bestsellers include the Roscida Heart hoop earrings ($228 in gold plating), diamond initial tag pendants ($395), made-to-order name pendants ($435), and an array of sculptural ear cuffs (ranging from $160 to $228).
The pop-up in Marylebone is an extension of Otiumberg’s office-store space in West London’s affluent Holland Park neighborhood, which has been a success: store sales grew 90% year-on-year during fiscal 2025, with the store accounting for 15% of the brand’s seven-figure annual revenue. (Wholesale contributes 20%, while direct-to-consumer (DTC) makes up the remaining 65%.)
As Otiumberg celebrates its 10th anniversary this year, it expects physical retail to propel its next stage of growth. “Marylebone is a jewel when it comes to retail. We feel the other brands that are there create beautiful adjacencies,” says Áine McCourt, CEO of Otiumberg. Neighboring stores include Ganni, multi-brand beauty retailer Space NK, and British lifestyle label Toast.
The pop-up is also a precursor to Otiumberg’s first flagship, which is opening this fall on King’s Road, one of the most popular shopping streets in Chelsea. “We expect a higher foot flow [in Marylebone compared to Holland Park], so it will be great training for our staff and give us a taste of what the flagship could be like,” says Wollenberg. “Customer experience is so important to us — making sure the customer feels they’re getting a luxurious experience no matter the price — so I think Marylebone is a training ground for that.”
