The Goldwin diamond band explores rhythm rather than hierarchy. Part of the Treowth Collection, its design emerged from the discovery of a small Saxon gold relic by Andrew & son Arthur – a fragment of time that has created a wealth of inspiration and quiet intrigue.
Rather than elevating a single diamond, the Goldwin works in sequence. A measured run of diamonds set into gold creates movement around the finger, catching light subtly as the hand turns. The result is a modern diamond band that feels composed, tactile, and confidently understated.
For those encountering Treowth for the first time, this is not a reworking of familiar diamond tropes. It is a contemporary response to ancient form.
DESIGN & FORM
The Goldwin is sometimes compared to a diamond eternity ring, but its structure is intentionally more fluid. Spacing, proportion, and sculptural metalwork allow light to move rather than overwhelm, giving the design a calmer visual rhythm.
Worn alone or paired, it reads as a diamond gold band, but with restraint that sets it apart from conventional eternity styles.
FULL SET / HALF SET OPTIONS
The Goldwin diamond band is available in two configurations:
- Full set – a continuous sequence of diamonds encircling the finger
- Half set – diamonds set across the upper face, with more gold beneath
Those familiar with jewellery terminology may recognise the half set as similar to a half eternity band. Here, the emphasis remains on balance, wearability, and proportion.
MATERIALS & CRAFT
Each Goldwin is handcrafted in your choice of 18ct gold or platinum. Diamonds are selected for consistency and life, then set with precision to maintain the rhythm that defines the design.
This is a gold diamond band designed for everyday wear. The metalwork is robust, refined, and finished by hand to ensure longevity and comfort.

GOLDWYN FAQS
Is this an eternity ring?

Is the Goldwin suitable for everyday wear?
