FAQ
How long will my order take?
Most made-to-order rings are delivered in around 8 weeks from order the order date. Ready-to-wear editions are delivered in roughly 3-5 working days. If you need to receive your order sooner, please get in touch and we’ll confirm if we can meet your deadline.
Can I receive a ring faster than 8 weeks?
Sometimes, depending on design complexity and our workload. If you're in a real hurry, your options include a sample ring loan or a ready-to-wear ring (3–5 days delivery).
What if I don’t know the ring size?
We can help - please see our sizing guides or contact us for discreet options.
Can you make custom sizes?
Yes. Smaller sizes are priced the same as the minimum listed; larger sizes may cost more. Please contact us to arrange.
Can I visit a showroom?
We're available by appointment at the London Diamond Bourse in London's Hatton Garden. Please book your consultation in advance.
How do I know materials are ethical?
We're committed to changing the world one gram of gold at a time, using our jewellery as an active vessel for good. This means working exclusively with recycled materials that are minimal in environmental impact or artisanally mined materials that proactively support mining communities. Every made-to-order piece comes with a certificate detailing material provenance and UK-based production.
Where is your jewellery made?
Entirely in the UK - cast in the Midlands, then set, finished and hallmarked in London's Hatton Garden.
Do you offer different finishes?
Yes - many of our designs can take on a matte and/or hammered finish. Please share your preference by adding a note at checkout or sending us an email.
What’s the difference between 9ct and 18ct gold?
9ct gold is slightly softer and paler in colour. We recommend 18ct for durability, with 14ct as a mid-range option. Learn more.
Will I be allergic to your jewellery?
Allergic reactions are rare. Our white gold uses palladium alloys, which are low-allergenic.
Is your jewellery vegan?
Mostly, aside from our sustainably harvested Tahitian pearls. Some traditional tools and materials (e.g. beeswax, leather) may also be used in workshops. Learn more.
How does your bespoke service work?
Please contact us to share your idea, budget and ideal timeline. We’ll create some initial designs for free (welcoming up to two free revisions). A £300 fee would apply if you weren't to proceed after this point. Production takes roughly 10–12 weeks. We request a 50% upfront payment to begin production, and the balance on completion. Learn more.
Can you remodel heirloom jewellery?
Yes - we specialise in remodelling existing pieces into new designs.
