This handmade fishtail set diamond band is designed to be worn as a wedding ring, an eternity ring, or a meaningful ring in its own right.

Set with nine round brilliant-cut diamonds, this ring has a total diamond weight of one carat. The diamonds are G colour and VS clarity, chosen for their brightness and balance of beauty and durability.

The fishtail setting is a distinctive and elegant detail. From the side, the setting fans out softly, echoing the shape of a fish tail. When light moves across the ring, these sculptural details can catch the eye like tiny heart shapes. Each diamond is held securely by four individual claws, rather than shared claws, creating both strength and definition between the stones.

This diamond band is handmade in the UK and can be made to any finger size. It is available in platinum, 18ct white gold, 18ct yellow gold, or 18ct rose gold.

You may also choose lab-grown diamonds instead of natural diamonds, or personalise the ring further by selecting a combination of coloured gemstones to reflect personal meaning, relationships, or style.

Elegant, luminous, and designed to be worn every day, this is a ring made to mark connection, commitment, or a moment worth remembering.
