Bespoke Engagement Rings.

A bespoke engagement ring is custom-designed exclusively for you. It allows you to choose every detail, from the design to the materials, ensuring a one-of-a-kind piece. It is deeply meaningful, tailored to your preferences, and made to perfectly symbolise your relationship. The ring is made to order and handcrafted from scratch according to a detailed design process, rather than from a premade or pre-designed product selection.

At LMK, bespoke engagement rings are all we do. Led by award-winning designer Lydia, we focus on creating the most meaningful, sentimental piece of jewellery you’ll ever own. While most bespoke designers expect you to bring the ideas, we know this can be overwhelming - especially for those new to jewellery or drawn to various styles. That’s where we come in. Instead of expecting you to know exactly what you want, we specialise in uncovering what’s most meaningful to you. We blend your personal story with timeless design elements, such as style, stone choice, and craftsmanship, to make your ring truly personal to you. With us, your ring will reflect your love story in a way that's both timeless and beautiful.

We are a luxury brand, and our craftsmanship reflects that, placing us outside of some couples' price ranges. The best thing about a bespoke engagement ring, is that this one-time investment is completely personalised to you - you control your budget by selecting each detail to match your taste and needs. We don't charge extra for bespoke design, nor do we have the costs associated with running a high street store, so if you can afford a luxurious ring, you don't pay a premium to work with us. We offer three all-inclusive options, two of which include a complimentary matched wedding ring, and if you’re not absolutely delighted, you don’t pay: Option One - LMK Exclusive: For budgets of £4,000 and above. A meticulously crafted, bespoke ring that captures your love story in a timeless, luxurious design. Option Two - LMK Elevated: For budgets of £7,000 and above. Designed to create a masterpiece of unmatched detail and artistry, with a complimentary matched wedding band in 18K yellow gold or platinum. Option Three - LMK Rarified: For budgets of £15,000 and above. A bespoke experience reserved for those seeking the rarest materials and the utmost in craftsmanship.

Start your journey with a complimentary bespoke design, tailored exclusively to your partner.

Including thorough analysis of you and your partner, most designs take 2 weeks to be sketched, digitised, and turned into a lifelike animated video and exact 3D replica for you to see and hold. Once you’ve fallen in love with your final design, you'll be invited to choose the perfect diamond, either in-person or online. The timing of this is therefore dependent on your own personal schedule and our diary. Once your diamond is chosen and your design is approved, our skilled artisans begin the process of bringing your ring to life, handcrafting it in our London workshop. Typically, this process takes 4-5 weeks. The exact time frame is discussed with you during your initial consultation and we'll keep you up-to-date throughout the process. Ready to get started?

We assess nine separate elements to determine exactly which style, size, and type of engagement ring is perfect for the wearer. Based on your responses to our initial questionnaire and a photo of your partner, we tailor your ring to meet both practical and aesthetic needs, ensuring it stands the test of time. We then blend these elements with a cherished memory or sentimental theme to create your timeless heirloom. We're so confident in our design process that we can offer a unique guarantee unavailable anywhere else - if either you or your partner are not absolutely delighted with your heirloom, you don't pay.

There are many checks and balances built into the LMK process which makes this virtually impossible. You'll receive a lifelike, exact 3D replica* of your ring which you can see and hold before committing. We don't believe you should have to pay for something unless it’s exceptional. If you and your partner aren't thrilled with the final piece, you don’t pay. Such is our confidence in our ability to support and protect your special moment. *Our replicas are shipped in unbranded packaging labelled ''batteries'' and fit through the letter box. You have the option to provide an alternative shipping address should this better meet your needs. Get started with your complimentary bespoke design:

You don’t need a clear vision. Uncovering your unique story in a way you and your partner will love is what we do. Once you've completed a brief questionnaire, we will intuitively capture your partner’s style and the emotions you wish to convey, taking your simple insights and transforming them into a timeless masterpiece.

If you have a clear vision of what you/your partner loves, that’s an excellent starting point. We specialise in taking your vision and elevating it into something truly exceptional. Please note that we do not offer plain diamond solitaires, as our focus is on creating personalised designs. This allows us to dedicate our time to clients seeking something more emotive and beyond what’s already available.

Yes, it would be an honour to be entrusted with a precious part of your heritage. Our process allows you to carry a piece of your family’s history forward while creating a new chapter in your own love story. Our master artisans are skilled in working with existing materials to craft a ring that is both modern and timeless.

Natural Diamonds In addition to sourcing cut and polished gems, we specialise in sourcing rough, uncut diamonds straight from mine, making us among the few diamond houses to enjoy 'first pick' before gems enter the wider market. We have established deep connections with artisanal mines globally, with all of our natural diamonds being selected in-house from ethical producers. Notable regions include: Botswana, Canada, Namibia (ocean). Lab Grown Diamonds As far as we know, we were the first specialists to introduce lab grown diamonds to the UK jewellery market, however the technology itself was developed in 1954. We specialise in slow-growth and single growth diamonds, which minimise the occurrence of strain and striation, both forms of disruption in the normal growth of diamond crystals which affect light performance. These can occur in natural diamonds and lab grown diamonds, but are prevalent in standard production lab grown diamonds.

No, we are a small independent brand focused entirely on creating made-to-order bespoke engagement rings.

If you'd like to meet in person, we offer appointments at two exclusive London locations: Our private member's club in Marylebone, West London, where you can enjoy a glass of champagne, or at our offices at the renowned diamond trading floor in central London. This diamond trading platform is recognised globally for its access to the most exquisite gems, and LMK clients receive exclusive, behind-the-scenes access by appointment.
