Thalassa | 0.75 ct Lab-Grown Diamond Toi et Moi Ring
The Thalassa Toi et Moi Ring explores connection through form rather than tradition.
A round brilliant diamond and a pear cut diamond sit opposite one another, framed by a sculpted wave of gold that curves naturally around each stone. Inspired by the movement of the sea, the flowing band creates softness while still holding the diamonds securely, giving the piece both structure and fluidity.
With a total diamond weight of 0.75ct, the stones are proportioned to feel balanced on the hand, noticeable without appearing heavy. The curved setting allows light to enter from multiple angles, giving the ring a natural brilliance that shifts subtly as the hand moves.
The silhouette is distinctive yet comfortable, designed to sit low enough for daily wear while remaining recognisable. Worn alone it feels intentional; paired with bands it becomes part of a layered look.
Each ring is handcrafted to order in Birmingham’s historic Jewellery Quarter in your choice of 9ct or 18ct white, yellow, or rose gold. Individually finished by experienced jewellers, every piece is carefully balanced for comfort, durability and proportion.
Rather than following tradition, Thalassa is a ring chosen for meaning, a reflection of two forms existing together, independent yet connected.
