Ring sizer loan

Not being able to visit us in person doesn't mean you're denied access to the best customer service we can offer. For a refundable deposit of £15 we'll lend you one of two types of ring sizing tool, along with some handy tips for measuring yourself up from home. Order your ring sizer loan.

Printable ring sizer

Alternatively, you could also try using our printable ring sizer. Use this with a ring that either you or the person you're purchasing for currently wears. It's best to choose a ring that's similar in style to the one you want to buy, too. Then, follow these instructions: 

1. Print this page at 100% size.

2. When setting your print options you must ensure the options to fit or shrink to page ARE NOT selected.

3. Print the document, then with a ruler or tape, measure the outer box to ensure it matches the dimensions marked.

4. Hold your selected ring against the circles on the chart.

5. Choose the letter that best matches the internal diameter of the ring.

6. This is the ring size you should order.

You can also download a PDF version of the ring sizer.

How long will my order take to arrive?

Our wedding bands and engagement rings usually take around eight weeks, from the order date, to be complete. If you need yours sooner then please get in touch; we'll let you know if we can meet your deadline. 

Do you have a showroom where I can try your wedding and engagement rings?

If you'd like to see our jewellery's extraordinary craftsmanship in person, try on some sample rings and get yourself measured up for size, you can visit us at our London showroom. We’re proud members of the London Diamond Bourse - a historic and exclusive jewellers’ institution in the heart of Hatton Garden, London’s famous jewellery quarter - and are available to meet here by appointment every Wednesday.

We can also take appointments at the St. Augustine's Arts Centre café in Brighton on Thursdays and the occasional Saturday morning.

How will I know if my chosen item is ethically sourced?

At Lebrusan Studio we're committed to using the most sustainable and responsibly sourced materials we can find, offering you a number of metal and gemstone options to choose from. All made-to-order engagement rings, wedding bands and bespoke commissions come with a unique certificate of authenticity and provenance, verifying the materials used and summarising the UK-based manufacturing process. Transparency is important to us, and we'll ensure that you know as much about the provenance of your special jewel as we do.

I cannot find my size on your website. Could you make the piece in a size bigger or smaller than what's listed?

All of our pieces are made to order, which means we can create them in whichever size you require. Requests for rings smaller than the minimum size listed on the website will be quoted at the same price as that smallest available size, whilst a larger size might cost a little extra. Please contact us directly to order a size that isn't readily available online.

Are the wedding/engagement rings available with matte and/or hammered finishes?

Yes, they are. We can apply a matte and/or hammered finish to many of our designs. On ordering, please drop us an email with your order number, specifying your preferred finish. Alternatively, please leave us a note at the checkout.

Is there any difference between 9ct gold and 18ct gold?

Yes. The difference is metal hardness; 9ct is softer and thus slightly less durable than 18ct. There's also a difference in colour when it comes to yellow gold; 9ct yellow is always slightly whiter than 18ct. We always recommend 18ct gold for wedding and engagement rings, as these are everyday pieces that must be resilient enough to withstand years of wear and tear. For the opportunity to reduce cost without compromising too much structural integrity, we also offer some of our wedding bands in 14ct gold. Learn more.

Can you make palladium wedding bands?

Yes, we can. Palladium is a white metal similar to 18ct white gold in appearance. Its durability and bright white hue make it an increasingly popular choice for men's wedding rings. Just drop us an email stating your preferred design and ring size, and we'll send you a quote in return. The current price for palladium is approximately 50% more than 18ct gold.

Will I be allergic to your wedding bands?

Allergies to gold or platinum are very rare, but naturally an allergic reaction is a slim possibility. To avoid adverse reactions, our white gold bands are made using an alloy of palladium, a very pure metal that very few people are allergic to. Learn more. 

Where will my jewellery be made?

Our jewels are crafted entirely in the UK, enabling us to champion traditional British craftsmanship and minimise the distance our materials travel, thus limiting the size of our carbon footprint. The casting process usually takes place in the Midlands, before finishing and hallmarking in small manufacturing workshops in Hatton Garden, London's famed jewellery quarter. 

Is your jewellery vegan? 

Aside from our sustainably harvested Tahitian pearls, our jewellery contains absolutely no direct animal products. That said, we cannot guarantee that the equipment or products employed throughout the manufacturing process are 100% vegan. For example, beeswax is sometimes uses to lubricate drills and saw blades, whilst leather is often present at jewellers' benches to catch small pieces of metal. Such are common practises for many jewellery manufacturers. On rare occasions, we may also transport particularly delicate pieces of jewellery inside small leather pouches. If you are vegan and wish to discuss this matter in more depth with us, please don't hesitate to reach out. 

How does your bespoke service work?

It's very simple. Take a moment to visit our bespoke jewels gallery to gather some inspiration, then drop us an email outlining what it is you’re after. It's always helpful if you indicate your budget and time frame in the first instance.

Once your vision is refined - either via an email discussion or consultation of some kind - a handful of designs will be presented to you. These initial designs are created free of charge, with up to two major revisions welcomed for free. After the first two design revisions, any further changes requested will incur an additional charge of £150 per revision. If you decide not to proceed with the process after this initial design phase, we will issue a design fee of £300 to cover our time and expenses. On approval of the final design, we request the first payment of 50% of the project costs. The final payment is then requested on on completion of the project. 

Some periods in the year are extremely busy for us, so please allow enough time for your creation to be manufactured; 10-12 weeks should be sufficient. You can learn more about our bespoke service here. 

How much does your bespoke service cost?

This is totally dependent on design. As a guide, our bespoke wedding bands  start at £1,500; our bespoke engagement rings start at around £3,000; and our bespoke jewels are generally priced from £3,000 upwards.

"I'm going to do it and I need a ring fast! Is there any way that I could receive a ring quicker than the eight-week lead time advised?"

This will depend on the complexity of the design you have in mind and the workload of our manufacturing workshops at the moment in question. We always try our hardest to ensure the quickest turnaround possible, priding ourselves on regular and informative communication throughout, but completion by an early and nominated date can never be 100% guaranteed; particularly not in the case of elaborate designs with many manufacturing stages. 

If time's really tight or you're struggling to commit to a particular design, our sample loan service involves renting a sample engagement ring, using it to pop the question, then initiating the manufacturing process once she's said "Yes." 

Alternatively, we also have a small collection of ready-to-wear engagement rings, any of which can be delivered in 3-5 working days.

"I'm ready to order an engagement ring but I have no idea which ring size to choose. Please help!"

Don't panic! There are a number of ways to solve the ring size mystery without rousing any suspicion. Check out this page and blog post for tips. 

"Can I incorporate an old piece of heirloom jewellery? I've already proposed and I'm now looking to transform my grandmother's old rings into her engagement ring."

Yes! As a jewellery brand that's passionate about sustainability and circularity, we love taking on the challenge of remodelling old jewellery and celebrating materials that are already above-ground. What's more, there's something really beautiful about breathing a second wind into a jewel that's steeped in sentimental value, celebrating family legacy and maintaining a connection with the past. Head to our Bespoke Remodelling Service page to learn more.
