A bold, radiant sweep of diamonds that wraps the finger in a clean, modern beam of light. This 3.2mm Astra-inspired band features larger round brilliants set in a smooth shared-prong structure, creating a bright, continuous line of sparkle with serious presence. It feels luxurious without being loud, refined without losing that warm, everyday ease.

The wider width gives the ring a confident glow, making it perfect as a standalone statement or a strong anchor in a stack. The diamonds sit closely together, catching light in crisp flashes that shift with every gesture. Paired with slim gold bands, pavé pieces, or a solitaire, it brings structure, dimension, and a glowing edge to the whole hand.

A luminous, sculpted ribbon of sparkle designed for those who want a little more light.

The 3.2mm width allows for larger round diamonds in a shared-prong arrangement, maximising brilliance while keeping the band smooth and wearable. The low-to-mid profile keeps the silhouette elegant and comfortable, while the shared-prong structure creates a clean, uninterrupted light line.

Wear it solo for a bold everyday sparkle or pair it with a slim plain band to create a chic, high-contrast duo. It also stacks beautifully under an engagement ring for bright but balanced framing.

All stones above 0.50 ct come with an official certificate. Our lab-grown diamonds are graded by the International Gemological Institute (IGI), detailing cut, clarity, color, and carat for complete confidence in your piece. For natural diamonds, available on special request, certification is issued by the Gemological Institute of America (GIA). Every certificate is a mark of authenticity, integrity, and lasting value — learn more under Certification.
