Bespoke Ring Design, Simplified

It’s natural to feel hesitant when stepping into the world of custom jewellery. Our role is to act as your guide, stripping away the mystery to show you just how simple and joyful the process can be.

You bring the initial inspiration: saved screenshots, a vintage silhouette, or a simple sketch. From there, we combine your unique vision with our technical expertise to create your perfect bespoke engagement ring.

The Sketches

After your consultation, we’ll map out your design with a simple sketch and detail your quote. This ensures our creative visions are aligned before any technical work begins.

The CAD

Next, your design comes to life via a detailed digital render. Complete with precise measurements, you can see your piece from every angle to ensure it's exactly as you pictured.

The Ring

Once your CAD is approved, production begins. Our jewellers meticulously cast, set, and polish your bespoke ring, with your finished future heirloom ready in around 5 weeks.

The First Step

We believe designing your ring should feel easy. There are no rigid rules here, only a supportive space to explore your ideas.

Your journey begins with a conversation with Olivia. Whether that’s in person, over the phone, on a video call, or via email, we work entirely to your schedule to pinpoint exactly what you love.

As a trained goldsmith, Olivia balances beautiful aesthetics with technical craftsmanship. By designing around how the ring will be worn, she ensures your future heirloom is perfectly tailored to your daily life.

FAQs

Your initial 30-minute consultation is completely relaxed and tailored to you. When you book, you choose how we connect: Olivia can call your mobile directly, host a private video consultation, or manage the entire design discussion via a dedicated email thread.

You don't need to bring anything at all! If you have saved Pinterest boards, screenshots, or rough sketches of design styles you love, we'd love to see them. If you are starting completely from scratch, Olivia will guide you through choosing metals, settings, and stone shapes to map out your perfect piece.

Not at all. We believe the bespoke jewellery journey should be an enjoyable, low-pressure experience. Your initial consultation is completely free, and there is absolutely no obligation to move forward with production until you are entirely in love with the final design concept and quote.

Because every Cornish Diamond Co. piece is entirely unique, your final investment depends on your choice of precious metals, stone specifications (like diamond carat and clarity), and design complexity. During our chat, we will openly discuss your budget and explore how to beautifully maximize your design within that target.

While every custom piece we create at The Cornish Diamond Co. is entirely unique, the complete journey from initial concept to final delivery generally takes around 8 weeks. This timeline can vary slightly depending on the complexity of your design, gem sourcing, and how quickly we finalise your concepts together.

Once you are completely happy with your design and your custom CAD images are officially signed off, the actual hand-crafting and production phase takes 5 to 6 weeks. This time allows our master craftspeople to meticulously cast, set, and polish your piece to perfection.

If you have a specific date or upcoming proposal deadline that you are aiming for, please let us know right at the start of your consultation. We will always do everything we possibly can to accommodate your timeline and work backward from your special day to make it happen.

Absolutely! We regularly collaborate with clients entirely remotely across the UK and beyond. Through video consultations, detailed digital sketching, and photorealistic 3D CAD rendering models sent directly to your inbox, no matter where you are located, you will feel entirely connected to the workshop throughout the entire creation process.

Planning a surprise can be nerve-wracking, but we are experts at secret ring sizing! During your consultation, Olivia can share clever, subtle ways to estimate their size using an existing ring or everyday clues. Most importantly, we offer a complimentary resizing service for our bespoke engagement rings to ensure that once the perfect moment arrives, the fit can be adjusted to absolute perfection.
