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 a good choice 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. It also looks beautiful in 18ct yellow gold which we also have in our collections.
