Design
This striking marquise diamond and sapphire engagement ring was thoughtfully commissioned entirely through WhatsApp. From viewing loose stones to exploring design concepts, our client was involved at every stage — all at a pace and time that suited him.
The process allowed him to shape something deeply personal, while keeping the final piece a complete surprise until the moment he proposed.
Unique Diamond Engagement Rings
Like an arrow from Cupid’s bow, our client was instantly drawn to this rare briolette-cut diamond, set within our one-of-a-kind Arrow engagement ring.
We can source — or commission the cutting of — exceptional diamonds, including lab-grown stones, in distinctive shapes, allowing you to create an engagement ring that feels entirely your own.
Not every engagement ring is a surprise. The experience of planning the ring together can be an unforgettable memory.
Customise Our Designs
Set with a grey sapphire surrounded by diamonds this platinum one of a kind engagement ring was inspired by moonflowers. Moonflowers are seductive and mysterious. They only blossom at night and they use their scent to attract pollinators. The sapphire has a beautiful sparkle with natural inclusions that give it a lunar quality. Natural inclusions are like a fingerprint making this gemstone totally unique.
All of our engagement rings can be customised, allowing you to create a truly unique ring that feels perfect for you. Rather than searching endlessly online, you can tailor every detail — from the metal to the gemstones and finer design elements — to create something entirely your own.
Here are some examples of how our flower ring has been customised to make each one unique.
Blue Sapphire - Diamond - Platinum
Amethyst - Diamond- Rose Gold
Blue Sapphire-Diamond- 18ct Yellow Gold
Morganite - Diamond - Rose Gold
Aquamarine- Diamond - Yellow gold - Flower Ring

Design Concept
We wanted to design a twist engagement ring that felt genuinely unique, so we created a piece that is as technically demanding as it is beautiful. The large pear-cut gemstone is partially rub-over set, with diamonds flowing around the band. Every stone is then carefully hand set under a microscope to ensure absolute precision and finish. Featured here in morganite and in aquamarine, you can have this special engagement ring design with any centre stone and it really changes how it looks.
Even traditional styles can be modernised to create a unique engagement ring.
