Marylebone, a district celebrated for its elegant streets, boutique retail experiences, and cultural richness, is welcoming a brilliant new addition. This summer, luxury ethical jeweller Lily Arkwright opens the doors to its flagship store in the prestigious Marylebone Square development, solidifying the brand’s commitment to British craftsmanship, innovation, and sustainable luxury.

For years, Lily Arkwright has led the charge in ethical fine jewellery—championing lab-grown diamonds, sustainability, and transparency. Now, their stunning new physical presence brings this mission to the heart of one of London’s most stylish and sought-after postcodes.

From Manchester to Marylebone: A Natural Evolution

Lily Arkwright’s journey began in Manchester, where the company quickly rose to prominence as one of the UK’s most trusted ethical jewellers. Known for their exquisite engagement rings and fine jewellery collections crafted using lab grown diamonds and Moissanite, the brand is recognised for redefining luxury without compromise.

Their Marylebone Square flagship store represents more than just a new retail location. It is a milestone that reflects the growing consumer demand for responsible jewellery, as well as Lily Arkwright’s evolution from an online-first business to a multi-channel, high-end luxury experience.

The store, designed with sustainability in mind, will not only showcase the brand’s core collections but also offer bespoke consultations, in-person styling appointments, and an immersive space to explore jewellery in its most conscious form.

Why Marylebone Square?

Positioned at the intersection of heritage and modernity, Marylebone Square is one of Central London’s most anticipated developments. With its elegant Georgian-inspired architecture, curated retail spaces, and upscale residential offerings, it embodies everything that makes Marylebone a magnet for tastemakers and innovators alike.

For Lily Arkwright, choosing Marylebone Square as the home for its flagship was both strategic and symbolic. The location aligns perfectly with their values: refined taste, timeless design, and conscious living.

As a brand rooted in British quality and innovation, this new boutique will sit comfortably among Marylebone’s finest offerings between artisan cafes, independent galleries, and luxury lifestyle brands.

All stones are independently certified by IGI or GIA, ensuring every purchase is accompanied by the same reassurance found in traditional high jewellery.

Moissanite and Coloured Gemstones

In addition to lab-grown diamonds, Lily Arkwright has long been a trusted name for moissanite jewellery a stunning alternative gemstone known for its exceptional sparkle and affordability. As the official UK distributor for Charles & Colvard Forever One Moissanite, the brand ensures that customers receive only the highest-quality options.

The Marylebone Square boutique will also highlight Lily Arkwright’s growing range of lab-created coloured gemstones, including emeralds, sapphires, and rubies. These vibrant, responsibly made stones offer a modern twist on tradition, making them perfect for everyday elegance or statement pieces.
