Quick Tips
- Measure at the end of the day, when fingers are largest.
- Snug, not tight — the ring should pass your knuckle with slight resistance.
- Wider bands (4mm+) fit tighter — consider sizing up half a size.
- Between two sizes? Always size up.

Our Vintage Round Halo Lab Grown Diamond Engagement Ring is a breathtaking homage to Art Deco craftsmanship. A stunning 1.50ctw round lab grown center diamond is framed by a pavé-set halo edged with bold milgrain beading — a signature of vintage fine jewellery — forming a beautiful octagonal silhouette that elevates the setting to a work of art. The 2.16 total carat weight is distributed across the halo and the diamond-set shoulders.
The wide split shank carries graduated prong-set round lab grown diamonds along both shoulders, each shoulder bordered by the same bold milgrain trim. The entire face of the wide band is covered in intricate hand-engraved floral and scrollwork motifs — a detail that rewards close inspection and makes this ring as captivating from the side as it is face-on. An open filigree gallery beneath the halo completes the vintage portrait.
Available in 10K/14K/18K White, Yellow, or Rose Gold and Platinum.
