About Diamond Eternity Rings

An eternity ring can celebrate an anniversary, the birth of a child, or elegantly complement engagement and wedding rings. Choose from full or half settings, channel or shared claw profiles, and an array of diamond shapes — including round brilliant, princess, emerald and French cut — to create a ring that reflects your style.


How to Choose Your Eternity Ring

Coverage & Silhouette

Full Eternity — Diamonds circle the entire band for uninterrupted brilliance and a modern, impactful look.
Half Eternity — Diamonds cover the upper arc, offering comfort, practicality and greater flexibility for future resizing.
Five & Seven Stone Bands — A classic, heritage style with generous presence and elegant finger coverage.

Setting Style

Shared Claw — Fine talon claws elevate each stone for maximum light return.
Channel — A smooth, contemporary profile that pairs seamlessly with engagement or wedding rings.
Bezel or Grain — Subtle vintage character with enhanced stone protection.

Diamond Shape

Round Brilliant — Exceptional fire and scintillation.
Princess — Clean, geometric modernity.
Emerald Cut — Refined lines and mirror like elegance.
French Cut — Antique charm with artisanal faceting.

For guidance on achieving the perfect balance of cut, colour, clarity and carat, explore the Pragnell Diamond Guide.

Metal & Finish

Choose platinum for its bright, enduring lustre, or 18ct yellow, white or rose gold for warmth and character. A comfort fit interior ensures effortless everyday wear.



Perfect Pairing

Eternity rings are made to harmonise. Wear yours as a luminous spacer, stack contrasting metals for depth, or mix diamond shapes and settings to create a signature Pragnell combination. Our consultants can advise in store or virtually.



Care, Sizing & Aftercare

To keep your ring pristine, we recommend professional cleaning and routine setting checks. Our workshops offer polishing, rhodium plating for white gold, and expert resizing guidance — with half eternity designs offering the most flexibility.
