Lab Ruby Round Octagonal Signet Ring | S925 Silver Baguette Channel Pavé Men's Statement

A vivid red ruby at the centre of an octagonal diamond signet. The ring that makes a statement without needing to explain itself.

A large round brilliant-cut lab-grown ruby in vivid, deeply saturated rose-red sits in a four-prong setting within a round brilliant diamond halo at the centre of a broad octagonal signet-style ring head — the eight-sided face gives the ring a bold, architectural silhouette associated with the great men’s jewellery houses. On each shoulder of the ring head, two vertical columns of baguette-cut diamonds in channel settings flank the central halo, their clean rectangular step-facets creating long, mirror-like reflections that frame the ruby with geometric precision. Below the ring head, two rows of round brilliant diamond pavé run along each tapered shoulder, creating a continuous field of diamond brilliance from the ring head to the band. The combination of the octagonal face’s architectural geometry, the baguette channel columns’ step-cut precision, and the pavé shoulders’ scattered fire creates a ring of exceptional visual complexity — a men’s statement ring with the construction quality of a fine jewellery house piece. Available in AU sizes H–T. At $450, this is the ruby signet ring that earns its place as the most considered piece in any man’s collection.

Why You'll Love It

• Octagonal signet-style ring head — the eight-sided face gives the ring a bold, architectural silhouette with the geometric precision associated with the great men’s jewellery houses; the octagonal format creates a ring head with genuine presence and weight on the finger, and the flat face’s broad surface area maximises the visual impact of the central ruby and diamond halo
• Baguette channel shoulder columns — two vertical columns of baguette-cut diamonds in channel settings on each shoulder of the ring head create a frame of clean, step-faceted geometric precision; the baguette’s rectangular silhouette and mirror-like reflections give the ring an architectural quality that round diamonds cannot replicate, and the channel setting’s flush surface creates a smooth, snag-free finish
• Round brilliant diamond halo and pavé shoulders — a round brilliant diamond halo surrounds the ruby at the centre, and two rows of round brilliant pavé run along each tapered shoulder; the combination of the halo’s concentrated brilliance and the shoulders’ continuous pavé creates a ring with diamond coverage across its full visible surface
• AU H–T sizing — available in a full range of Australian ring sizes from H to T, covering the full range of men’s finger sizes; please refer to our Ring Size Guide to find your perfect fit before ordering
• Guilt-free luxury — lab-grown rubies share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
