A 3 carat oval lab-grown diamond set in platinum with a bold east–west orientation. Designed and crafted in Britain, this modern ring is a celebration of brilliance, strength, and meaningful luxury.
This ring takes a classic oval diamond and reimagines it with a contemporary twist. Set east–west across the finger, the 3 carat lab-grown diamond becomes a line of light, sleek and modern yet timelessly elegant.
Crafted in platinum, the most enduring of precious metals, the design balances strength with purity. The lab diamond itself carries both scale and significance — chosen not only for its exceptional sparkle, but also for what it represents: a new era of beauty created with responsibility.
Designed and crafted in Britain, this piece embodies artistry, precision, and a modern vision of the future of sustainable jewellery.

FAQ
Can this ring be customised with different gemstones?
Yes. The east–west design is especially versatile, and works beautifully with diamonds, sapphires, rubies, emeralds, or other gemstones of your choice.
Is it possible to create this design in different carat sizes?
Absolutely. Whether you prefer a subtle statement or a bold centrepiece, the setting can be tailored to suit your ideal diamond or gemstone size.
What makes the east–west setting unique?
Unlike traditional north–south settings, the east–west orientation emphasises the stone’s length and creates a striking, contemporary line of brilliance across the finger. It's ideal if you want a large gemstone and you want to stack other rings next to it, such as a wedding ring or eternity ring.
How do lab-grown diamonds compare to mined diamonds?
Lab-grown diamonds are chemically and optically identical to mined diamonds, offering the same brilliance and durability with the added benefit of sustainable sourcing.
Why is platinum recommended for this design?
Platinum’s natural strength and purity make it an ideal choice for showcasing significant gemstones. Its durability ensures the ring will be treasured for generations.
