Additionally, you can choose for us to craft your ring in platinum or 18-carat yellow gold, and whether to include diamond-set shoulders.

We will ask for a ring size; however, if the proposal is a surprise, we can work to an estimate. We offer complimentary resizing on all engagement rings. f you have access to a ring your partner usually wears, this can offer a helpful starting point, supported by our ring sizing guide.

This ring will be handmade by James in our Hertfordshire workshop and by trusted London craftsmen on Bond Street. We typically require a lead time of 6–8 weeks. Once complete, we will hallmark your ring in London before delivery or collection.

A round brilliant cut diamond halo engagement ring is a beautiful choice for those drawn to timeless jewellery. The soft, symmetrical form of the round brilliant cut creates a balanced, refined aesthetic while maximising light return and brilliance. This ring is perfectly suited to those who value tradition, harmony and enduring style.

We offer complimentary engraving inside the band, allowing you to keep a meaningful date or message close.

Design and materials

We work with ethically sourced natural diamonds from trusted suppliers. We will guide you in selecting a GIA-certified round cut diamond within the colour range F/G and clarity VS2/SI1.

Round claws secure the centre diamond, while the accent stones are set within a castle setting, enhancing the ring’s soft yet refined character.
