Lab Diamond Round Brilliant Square Halo Engagement Ring with Pavé Shoulders in S925 Sterling Silver

A circle inside a square. The geometry of the proposal ring, reconsidered.

This lab-grown diamond round brilliant square halo engagement ring with pavé shoulders in S925 sterling silver is the only diamond engagement ring in the collection with a square halo — and that distinction matters. Where round halos echo the form of the stone they surround, a square halo creates a deliberate contrast: the round brilliant diamond’s continuous curves set against the clean right angles of the cushion-square halo, the circle inside the square producing a geometric tension that round-in-round designs don’t produce. The halo itself is set with closely placed round brilliant stones along all four sides, its corners softly rounded in the cushion-square form that gives it a contemporary quality without losing the precision of the square outline. The pavé shoulders extend the brilliance from the halo down the band on both sides, so that the ring catches light from every angle — face-on, in profile, and from across the room. At AUD $1,012.50, it is the engagement ring for the person who wants the classic round brilliant diamond and a setting that does something the others don’t.

Why You’ll Love It

• Square halo: the geometric contrast that round halos don’t produce — the cushion-square halo creates a deliberate contrast with the round brilliant diamond at its centre — circle inside square — producing a geometric tension and visual interest that round-in-round halo designs don’t produce; the only square halo diamond engagement ring in the collection
• Round brilliant diamond: the most light-efficient cut at the centre of the square — the round brilliant’s 57 or 58 facets return light in every direction, producing the continuous full-spectrum fire that makes it the most chosen diamond cut for engagement rings; inside the square halo, the contrast between the stone’s curves and the halo’s angles is immediate and considered
• Pavé shoulders: brilliance that extends from the halo to the hand — closely set stones along both shoulders of the band carry the diamond’s brilliance from the square halo down the finger on both sides; the ring catches light from every angle — face-on, in profile, and from across the room
• Cushion-square halo form: contemporary precision with softened corners — the halo’s softly rounded corners give it a contemporary quality that hard-square halos don’t have, while retaining the clean square outline that makes the geometric contrast with the round brilliant work; a considered detail that makes the ring wearable every day, not only on occasions
• Skin-friendly S925 sterling silver — hypoallergenic, durable, and finished to a lasting high-polish lustre that keeps the square halo and pavé shoulders looking precisely as intended, from the proposal to the decades that follow
