Bespoke Diamond Engagement Rings

Signature silhouettes

Discover solitaire engagement rings in their purest form, halo engagement rings that catch every kind of light, trilogy (three-stone) engagement rings with their quiet symbolism of past, present and future, dreamy two-stone (toi et moi) engagement rings for a love story told in pairs, and vintage-inspired engagement rings with the romance of another era. Drawn to something rarer? Our unique engagement ring designs are crafted for those who'd rather write their own.

Every Deltora engagement ring can be set with the diamond of your choosing: an ethically sourced natural diamond, or a lab grown diamond of the same exquisite fire, brilliance and grade. From there, you'll choose your diamond shape — round brilliant, oval, emerald, pear, cushion, marquise, radiant or princess — your carat weight, and your precious metal in 18ct yellow gold, white gold, rose gold or platinum. The result feels effortless. (The craft is anything but.)

Every Deltora engagement ring is handcrafted to order by master jewellers, with the kind of detail you only get when something is truly made for one person. Choose a design you love and our diamond concierge will guide you through every nuance — stone selection, setting style, the subtle flourishes that make a ring feel inevitable. The finished piece doesn't feel bought. It feels made.

Find a style that feels right and select Enquire. Our diamond concierge will be in touch to talk diamonds, design and timelines — and to ensure your ring is finished long before the moment that matters most.
