Lab Sapphire Emerald Cut Square Halo Ring with Pavé Shoulders in S925 Sterling Silver | Art Deco

Square inside square. Deep royal blue in a frame of white light. The ring that speaks in straight lines.

This lab-grown sapphire emerald cut square halo ring with pavé shoulders in S925 sterling silver is built around a design logic that is immediately distinctive: a square emerald-cut lab sapphire in deep royal blue, its step-cut facets producing a quality of light that brilliant cuts don’t — broad, mirror-like flashes of colour rather than the scattered sparkle of a round brilliant — set inside a square pavé halo whose form echoes the stone’s own geometry precisely. Square inside square: the halo’s clean right angles align with the emerald cut’s corners, creating a geometric coherence that round-stone-in-square-halo designs approach but don’t fully achieve. The step cut’s large, open facets give the deep royal blue a depth and clarity that is the hallmark of Art Deco jewellery — the period that understood better than any other that a coloured stone and a geometric setting are most powerful when their forms reinforce each other. The pavé shoulders extend the white light from the halo down the band on both sides. At AUD $198, it is the most architecturally considered sapphire ring in the collection.

Why You’ll Love It

• Emerald cut: step-cut geometry that brilliant cuts don’t replicate — the emerald cut’s large, open step-cut facets produce broad, mirror-like flashes of deep royal blue rather than the scattered sparkle of a brilliant cut; a quality of light that is immediately distinctive and that gives the sapphire a depth and clarity that smaller facets don’t produce
• Square inside square: geometric coherence between stone and halo — the square emerald cut and the square pavé halo share the same geometry — their corners align, their right angles reinforce each other — creating a design coherence that round-stone-in-square-halo combinations approach but don’t fully achieve; the most geometrically precise sapphire ring in the collection
• Art Deco design language: the period that understood coloured stone geometry — the combination of a step-cut coloured stone and a geometric halo is the defining design language of Art Deco jewellery; here it is executed with the clean lines and precise proportions that make Art Deco pieces as contemporary today as they were a century ago
• Pavé shoulders: white light that extends the halo down the band — closely set stones along both shoulders carry the halo’s white light down the finger on both sides, so that the ring catches light from every angle — face-on, in profile, and from across the room
• Skin-friendly S925 sterling silver — hypoallergenic, durable, and finished to a lasting high-polish lustre that keeps the square halo and emerald-cut sapphire looking their best for every occasion
