The Sloane Ring – Solitaire Engagement Ring

Made to order solitaire engagement ring

As we make this ring to order, we will source a round brilliant diamond 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.

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. If you have access to a ring your partner usually wears, this can offer a helpful starting point, supported by our ring sizing guide.

Your 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

The hidden diamonds within this timeless solitaire introduce a quiet layer of intrigue. Visible only as the ring moves, they offer a subtle flash of light beneath a classic single stone silhouette. For an alternative interpretation of hidden detail, explore our Putney Ring.

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 brilliant cut diamond within the colour range F/G and clarity VS2/SI1. This design can be handcrafted in platinum or 18-carat yellow gold.

A four-claw setting elevates the centre diamond above a clean light gap, encouraging maximum brilliance. The hidden diamonds along the finger rail sit in a fine pavé setting, creating a discreet shimmer beneath the solitaire.
