Zirelle Emerald Halo Studs – Lab-Grown Emerald & Lab-Grown Diamond

Why You'll Love It

The Zirelle Emerald Halo Studs are the most wearable piece in our emerald collection — a round lab-grown emerald at the center of each stud, surrounded by a continuous pavé halo of D–F colorless round brilliant lab-grown diamonds, finished with a milgrain edge that gives the setting a refined, vintage-adjacent detail, all in solid 14K gold with a secure pushback closure. At 6.8mm across, the Zirelle is substantial enough to read as a serious piece of fine jewelry from across a room — the vivid green emerald and the surrounding diamond halo create a stud that commands attention — and refined enough to wear every day, with any outfit, in any setting. The pushback closure holds each stud securely against the ear, the flat butterfly back sitting flush against the lobe for all-day comfort.

The Milgrain Edge

The milgrain edge — a continuous row of tiny gold beads rolled around the outer rim of the setting — is one of the most refined details in fine jewelry, associated with the Edwardian and Art Deco periods when milgrain was used to soften the transition between the setting and the skin. In the Zirelle, the milgrain edge frames the diamond halo with a delicate border of gold beads that catches light independently of the diamonds, adding a third layer of brilliance to the stud: the vivid green emerald at the center, the white fire of the diamond halo, and the warm glint of the milgrain edge. The milgrain also gives the Zirelle a vintage quality that distinguishes it from a plain halo stud — a detail that rewards close attention.

Why Lab-Grown Emerald?

Natural emeralds are among the most included of all gemstones — the internal fractures and inclusions that give natural emeralds their character also make them fragile and difficult to set. Lab-grown emeralds are chemically, physically, and optically identical to natural emeralds — the same crystal structure, the same refractive index, the same vivid green color — but grown in a controlled environment that produces stones with fewer inclusions, greater clarity, and greater durability than most natural emeralds at any price point. The lab-grown emeralds in the Zirelle are eye-clean and vivid: stones that look like the finest natural emeralds without the fragility or the ethical concerns of mined stones.

Why D–F Diamonds?

The diamond halo in the Zirelle is set with D–F colorless round brilliants because the contrast between the vivid green emerald and the surrounding diamonds is the visual heart of the design. D–F colorless diamonds ensure that the halo reads as pure white fire against the vivid green center, maximizing the color contrast and the visual impact of the stud. In yellow gold, this contrast is most dramatic — warm metal, cool diamonds, vivid green emerald. In white gold, the diamonds and metal merge into a single field of cool brilliance that makes the emerald appear even more saturated. In rose gold, the warm blush metal gives the colorless diamonds a romantic quality that complements the vivid green center beautifully.

Our Story

In our Queens atelier, the Zirelle was designed as the everyday emerald stud — a piece that could be put on in the morning and worn through everything the day brings, without adjustment, without worry, without compromise. The round emerald was chosen for its symmetry: a round stone in a round halo is the most balanced, most wearable stud configuration in fine jewelry, a design that works with every face shape, every ear shape, every outfit. The milgrain edge was chosen for its history — a detail that connects the Zirelle to a century of fine jewelry craftsmanship while keeping it entirely contemporary. Named for the Old French zire — a small, bright thing — the Zirelle is a stud that earns its place in the daily rotation.
