Callista Arc | 1.40ct Lab Grown Diamond Necklace
The Callista Arc Necklace is designed around balance, not symmetry for its own sake, but harmony between different forms.
A sequence of round, pear, marquise and emerald-cut lab grown diamonds is arranged along a gentle curved bar, allowing each stone to contribute its own character to the piece. The variation in shape creates movement across the neckline, so the necklace catches light gradually rather than all at once.
With a total diamond weight of 1.40ct, the stones are individually set to maintain definition between each cut while still reading as a single composition. The curved form follows the natural line of the collarbone, giving the necklace presence without feeling heavy or formal.
It sits cleanly against the skin, making it comfortable for everyday wear, yet distinctive enough to elevate evening styling. Worn alone it feels considered; layered, it anchors the rest of your jewellery.
Each Callista Arc Necklace is handcrafted to order in Birmingham’s historic Jewellery Quarter in your choice of 9ct or 18ct white, yellow, or rose gold. Every piece is individually finished by experienced jewellers, ensuring proportion, polish and balance.
Rather than a traditional diamond line necklace, Callista Arc is a modern composition, designed to feel intentional, personal, and effortless to wear.
