Callista Line | 0.65ct Lab Grown Diamond Necklace
The Callista Line Necklace is a study in proportion and restraint.
A sequence of round, pear, marquise and emerald-cut lab grown diamonds is arranged along a slender horizontal bar, allowing each shape to remain distinct while forming a single balanced composition. The variation in cuts creates a soft movement of light across the neckline rather than a single concentrated sparkle.
With a total diamond weight of 0.65ct, the scale is intentionally refined, noticeable when worn, yet never overpowering. The bar follows the natural line of the collarbone, sitting flat against the skin so it feels secure and comfortable throughout the day.
Designed to layer effortlessly but strong enough to wear alone, Callista Line becomes an easy signature piece, the necklace you reach for without needing an occasion.
Each piece 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 result is balanced, precise and quietly elegant.
Rather than a statement, Callista Line is a considered detail, subtle, modern and designed to be worn often.
