Not sure where to begin? Book a consultation and we’ll guide you to the perfect ring.
Modern Wisdom. Eternal Light.
Striking in its minimalism, The Line of Prometheus channels bold intellect and refined symbolism. A singular horizontal baguette-cut diamond sits at the heart of a brushed matte band, intersected by a sharp polished groove - a clean line of brilliance that evokes a divine spark.

The architectural setting offers modern elegance with mythic soul, perfect for the wearer who values clarity, intention, and legacy.
Whether chosen as a men’s diamond wedding ring, a statement piece, or a mark of personal transformation, The Line of Prometheus is a quiet revolution, worn with purpose, forever.

THE FOUR PILLARS
Every Astella wedding ring is available in 18ct yellow gold, 18ct white gold, 18ct rose gold, and platinum.
Each metal wears differently over time, platinum develops a natural patina, while gold retains its colour and brightness with care. Not sure which to choose? Our metal guide covers everything, or speak to our team and we'll help you decide.
All Astella diamond wedding rings are set with lab-grown diamonds, real diamonds with the same optical, chemical, and physical properties as mined stones. Lab-grown diamonds allow us to offer exceptional quality at a price that reflects the craft.
Natural diamonds are available on request. Speak to us before ordering if you'd like to discuss stone options.
Every ring we make is covered by the Astella Ever After Lifetime Guarantee, a lifetime commitment to the quality of our craftsmanship.
This includes complimentary resizing within the first year and a professional clean and polish whenever you need it. We're based in Birmingham's Jewellery Quarter and you're always welcome to bring your ring in.
All Astella wedding rings are made to order and typically ready within 4–6 weeks. Your ring is delivered via Royal Mail Special Delivery, fully insured and tracked from our studio to your door.
To keep your ring looking its best, remove it during heavy manual work and avoid contact with harsh chemicals. We're always here if you need advice, reach us on WhatsApp or at hello@astellajewellery.co.uk
