Callista Mosaic | 0.70ct Lab Grown Diamond Ring
The Callista Mosaic Ring is designed as a composition rather than a single focal stone.
Emerald, oval and marquise-cut lab grown diamonds are arranged in a flowing sequence across the band, allowing each shape to remain distinct while forming a balanced silhouette. The variation in cuts creates soft movement of light across the hand, giving the ring presence without relying on height or bulk.
With a total diamond weight of 0.70ct, the scale is refined and wearable. The low profile setting keeps the diamonds protected while allowing light to enter from multiple angles, creating natural brilliance as the hand moves.
The band sits comfortably against the finger and layers easily with other rings. Worn alone it feels modern and considered; paired with bands it integrates seamlessly, adding detail without overpowering.
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, the piece is balanced for comfort, durability and everyday wear.
Rather than a traditional diamond band, Callista Mosaic is a ring chosen for design, subtle, distinctive and easy to wear often.
