The Knightsbridge Radiant Ring – Radiant Cut Halo Engagement Ring

Made to order radiant cut halo engagement ring

As we make this ring to order, we source a radiant cut diamond and accompanying accent stones to suit your preferences and budget. Our diamond buying guide outlines the key qualities we’ll discuss with you — referred to as the 4Cs — to help you choose the right diamond for you.

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.

Crafted for life’s stories

A radiant cut halo engagement ring is for those drawn to a rectangular diamond ring yet also want exceptional brilliance.  The elongated form offers a sense of structure, while the surrounding halo brings light and softness to the design. It is a style often chosen by those who like boldness, yet value elegance and considered detail. It is both expressive and timeless with a natural sense of glamour.

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 radiant cut diamond within the colour range F/G and clarity VS2/SI1.

Talon claws secure the radiant cut diamond, while the accent stones are set within a castle setting to enhance the uninterrupted sparkle.
