From the images, Perry’s engagement ring looks to be an oval purplish-red ruby. The centre gemstone is surrounded by round diamonds, framed with a delicate milgrained halo.
Milgrain is a raised metal beading effect, usually featured along the edges of a design, serving as a textured frame and highlighting the stone at its centre. This design element is often seen in antique and vintage-inspired jewellery design. Crafted in warm yellow gold, Katy is right on trend with yellow gold engagement rings seeing a significant come back over the last few years.
Adored by members of the British royal family and celebrities alike, the versatility of halo engagement rings is appreciated worldwide – the most famous being the blue oval sapphire diamond halo engagement ring, now worn by Catherine, Duchess of Cambridge, having previously belonged to Princess Diana.
Perhaps as a nod to his British heritage, Katy’s engagement design bears similarities to Princess Eugenie’s Padparadscha sapphire engagement ring. While the Princess’ ring holds a lighter, softer hued centre stone, Perry’s gemstone has a deeper tone with slightly larger diamonds on the halo, reflective of her bold sense of style.
