A Bespoke Ceylon Sapphire & Diamond Engagement Ring
This custom engagement ring was created for a client who loved deep blue gemstones, clean lines and the elegant proportions of an emerald cut.
The brief called for a ring with strong geometry, refined Art Deco influence and a sense of balance on the hand. We sourced a selection of sapphires and diamonds for the client to consider, before developing the final design around a 3.67ct emerald-cut Ceylon sapphire.
The finished ring was handmade in 18ct yellow gold, with trapeze step-cut diamonds framing the centre stone.
Design Development & Brief
The design began with stone selection. Several blue sapphires were sourced so the client could compare colour, cut and character before choosing the centre stone.
Once the sapphire had been selected, Matthew designed the ring around its strong emerald-cut shape. Trapeze step-cut diamonds were chosen to continue the clean architectural lines and create a balanced transition from the centre stone into the band.
The concept was first explored through sketches, then refined with CAD modelling so the proportions, stone placement and overall silhouette could be reviewed before the ring was handmade.
From gemstone selection to sketching and CAD refinement, each stage was used to balance the bold centre sapphire with the clean geometry of the diamond side stones.
Inside the Workshop
The ring was constructed by hand in 18ct yellow gold. Each setting was made and checked individually to ensure the sapphire and diamonds sat securely and in proportion.
The settings were then assembled, soldered together and refined before the diamonds were set. The centre sapphire was set last, completing the structure of the ring and allowing the finished piece to be checked for alignment, security and balance.
The Finished Piece
The completed ring is bold, structured and deeply personal. The rich blue Ceylon sapphire gives the piece its colour and presence, while the step-cut diamonds add symmetry, brightness and refinement.
The yellow gold setting brings warmth to the design and contrasts beautifully with the saturated blue of the sapphire. The result is a distinctive engagement ring with a strong architectural feel, made to suit the client’s taste rather than follow a standard design. The result is a ring with presence, but also proportion — designed to feel personal, wearable and unmistakably made for its owner.

One-of-a-kind engagement ring
This project highlights how a carefully sourced feature gemstone can guide the entire design of a bespoke engagement ring. The deep blue Ceylon sapphire, step-cut diamond shoulders and warm yellow gold construction work together to create a ring with strong geometry, balance and presence.
While the design was refined through sketches and CAD, the ring itself was handmade and assembled at the bench. Each setting was individually crafted and checked around the stones, resulting in a distinctive engagement ring made around the client’s brief, chosen gemstone and personal style.
