Lab Ruby Emerald Cut Square Halo Stud Earrings | S925 Silver Diamond Frame

Deep red. A clean square of diamonds. The earring that works with everything and elevates anything.

A large emerald-cut lab-grown ruby in vivid, deeply saturated red sits in a four-prong setting within a square round brilliant diamond halo in polished S925 Sterling Silver. The rectangular step-cut of the ruby creates a bold, architectural centrepiece within the clean square frame, and the cut-corner square outline of the halo gives the earring a strong, geometric silhouette that is immediately distinctive. At $112.05, this is the ruby stud that belongs in every collection — the one you reach for first.

Why You'll Love It

• Emerald-cut ruby — the rectangular step-cut maximises the ruby’s vivid red colour and creates a bold, architectural focal point within the square halo; the long, open facets give the stone a depth and intensity that a round or princess cut cannot replicate
• Square diamond halo — round brilliant diamonds trace the full square outline of the earring, creating a clean, geometric frame that gives the stud a strong, modern silhouette; the cut-corner square shape is more distinctive than a standard round halo
• Compact everyday stud — sits flush and secure against the ear; substantial enough to be noticed, compact enough for all-day wear; the kind of earring that pairs with everything from a simple white shirt to a formal dress
• Accessible entry point — at $112.05, this is fine jewellery at a price that makes it an easy decision; a genuine ruby and diamond halo stud that wears and looks like a piece worth far more
• Guilt-free luxury — lab-grown rubies share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
