Lily Arkwright
A showroom on Marylebone Square and every price on the website, with engagement rings in lab-grown and natural diamonds, moissanite and coloured gemstones.
Marylebone Square, 5 Aybrook St, W1U 4EL · 02045475144
Every price is on the website, and one Marylebone showroom lets you compare lab-grown and natural diamonds, moissanite and coloured gemstones side by side. If you want bespoke and have a date, allow up to six weeks for production once the design is signed off.
Every Stone Type, Priced in Public
Lily Arkwright’s London showroom is on Marylebone Square, with a second showroom in Manchester, and the business launched in 2015. Engagement rings lead the range, in lab-grown diamonds, natural diamonds, moissanite and coloured gemstones, alongside wedding rings and fine jewellery. They are an authorised retailer for Chatham coloured gemstones and for Charles & Colvard moissanite.
Prices are on the website. The lowest-priced engagement rings were £668 when we checked in November 2026, for a 0.23ct round moissanite solitaire in 9k white gold, and every other price depends on the stone, its size, the metal and the design. Finance is available through Dopple and Klarna. Being able to price a ring at home, before booking anything, changes how you can shop.
Moissanite is not a cheap diamond. It is a different stone with more fire and less hardness, and anyone selling it honestly will tell you so.
London Engagement RingsBook a Consultation, or Just Buy It
You can book a consultation at the Marylebone or Manchester showroom, or a WhatsApp video call from home. Booking ahead is recommended so a specialist is free, and walk-ins are welcome when one is. You can also order online.
Bespoke runs in three stages. At the concept stage the team turns your ideas, sketches or images into an agreed brief, for a one-off £90 fee. Next come computer renders and 3D images of the ring, with unlimited changes before you sign off, and a wax prototype is available as an optional extra for £60. Once the design is approved, production usually takes up to six weeks. Bespoke commissions start from £2,000, so if you are working to a proposal date, confirm the schedule for your piece at the start.
Eligible purchases can be returned within 50 days of delivery, unworn and in the original packaging; engraved, personalised, bespoke and made-to-order pieces are excluded. The lifetime warranty covers manufacturing and processing defects, subject to its terms, and every ring comes with one free resize in the first year and free insured delivery. Lab-grown diamonds come with a certificate from an independent laboratory.
The Right Buyer for Lily Arkwright
This suits someone who wants to compare stone types before choosing one: lab-grown and natural diamonds, moissanite and coloured gemstones, all priced before you book anything. If your budget is around £1,500 and you want a visibly substantial stone, lab-grown or moissanite is how that happens, and you can look at a natural diamond alongside to judge the difference for yourself.
It also suits anyone considering moissanite seriously rather than as a compromise. Being an authorised Charles & Colvard retailer means you are buying a known quantity rather than an unbranded stone of uncertain quality.
And it suits anyone who wants a design of their own. Bespoke starts from £2,000, and you approve renders of the ring before anything is made.

How much are Lily Arkwright engagement rings?
Prices are published on the website and depend on the stone, its size, the metal and the design.

Bespoke commissions start from £2,000, and finance is available through Dopple and Klarna.
What is the difference between moissanite and a lab-grown diamond?
A lab-grown diamond is chemically identical to a mined one. Moissanite is a different mineral entirely, with more fire and slightly lower hardness, and it costs considerably less. Lily Arkwright sell both and are an authorised Charles & Colvard retailer for moissanite.
Do Lily Arkwright sell natural diamonds?
Yes. There is a dedicated natural diamond engagement ring collection, alongside lab-grown diamonds, moissanite and coloured gemstones, and the Marylebone showroom carries natural diamond rings too.
What is their returns policy?
