Callista Axis 0.50ct Lab Diamond Necklace
Not sure where to begin? Book a consultation and we’ll guide you to the perfect piece.
The Callista Axis Necklace is a refined study in symmetry and structure — a horizontal composition of mixed-cut lab grown diamonds totalling 0.50 carats, set with precision along a clean gold bar silhouette.
Featuring round and emerald-cut lab diamonds arranged in balanced alignment, this piece embodies modern minimalism with a distinctly architectural edge.
Crafted in your choice of 9kt or 18kt white, yellow or rose gold, Callista Axis is designed to sit effortlessly along the collarbone, delivering sharp brilliance and understated luxury.
This is everyday fine jewellery — elevated.

THE FOUR PILLARS
Every Astella fine jewellery piece is available in sterling silver, 18ct yellow gold, and 18ct rose gold.
Each piece is finished by hand in Birmingham's Jewellery Quarter, where the same care given to our engagement rings goes into every fine jewellery piece we make.
All Astella fine jewellery is set with lab-grown diamonds, real diamonds in every sense, with the same optical, physical, and chemical properties as mined stones. Lab-grown diamonds allow us to offer exceptional quality at a price that reflects the craft, not the mining. Every stone is hand-selected by our team before it goes into your piece.
Every Astella piece is covered by our Ever After Lifetime Guarantee, a commitment to the quality of our craftsmanship for as long as you own the piece. If something isn't right, we'll always make it right. We're based in Birmingham's Jewellery Quarter and you're welcome to bring your piece in at any time for a professional clean and polish.
All Astella pieces are made to order and typically ready within 4–6 weeks. Your order is delivered via Royal Mail Special Delivery, fully insured and tracked from our studio to your door.
Packaging is plain and unmarked on the outside. To keep your piece looking its best, store it separately in the Astella box it arrives in and avoid contact with perfume, lotions, and water where possible. We're always here if you need advice on caring for your piece, reach us on WhatsApp or Email.
Discreet Delivery
Your order arrives in plain, unmarked packaging — no Astella branding on the outside, and the return address uses a personal name. Perfect for keeping a surprise exactly that.
