Made to order round brilliant trilogy engagement ring
As we make this ring to order, we source three round brilliant cut diamonds 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 diamonds 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.
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 trilogy engagement ring beautifully represents the past, present and future, making this balanced three-stone design a meaningful expression of enduring love. It is a sentimental choice for those who wish to incorporate symbolism into their ring, with the option of a diamond-set finger rail to add further personal significance. For example, by using a chosen number of stones to mark a special moment or milestone. This design is also perfect for those drawn to the brilliance of round cut diamonds, where each stone plays a distinct and pivotal role in the ring’s overall composition.
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 GIA-certified round brilliant cut diamonds within the colour range F/G and clarity VS2/SI1. This design can be handcrafted in platinum or 18-carat yellow gold.
Diamond sizes can be tailored to achieve your preferred balance between the centre and side stones, creating a harmonious three-stone ring with refined, classic appeal. Delicate round claws secure each diamond, complementing the soft, timeless character of the design.
