Collection: Solitaire Engagement Rings

The solitaire setting places a single diamond at the centre of the ring with nothing else to compete with it. No additional stones, no surrounding detail — the focus is entirely on the diamond. Its cut, its clarity, its presence. It is the most direct expression of what an engagement ring can be.

The setting itself shapes the character of the piece. A four-prong cradles the stone with minimal interruption. A six-prong holds it with more security and a rounder appearance. A bezel wraps the girdle in metal — clean, contemporary, considered. Each brings something different to the same principle.

Every Carat House solitaire engagement ring is made to order. Available in lab and natural diamonds, across all cuts and carat weights, in 18k white, yellow or rose gold and platinum. Delivered across Australia with free shipping.
