Lab Ruby Princess Cut Solitaire Ring | S925 Silver Diamond Pavé Band

One stone. Four prongs. A diamond band that knows its role. This is the ruby ring in its purest form.

A large princess-cut lab-grown ruby in vivid, deeply saturated rose-red sits in a four-prong solitaire setting on a round brilliant diamond pavé band in polished S925 Sterling Silver. The princess cut — a square with sharp corners and brilliant-style faceting — maximises the ruby’s colour saturation and creates a bold, architectural centrepiece that commands the finger without any additional halo or side stones. The diamond pavé band adds a continuous line of brilliance that frames the ruby from below, keeping the design clean and the focus entirely on the stone. At $171, this is the ruby solitaire that belongs in every collection.

Why You'll Love It

• Princess-cut ruby — the square brilliant cut creates a bold, architectural centrepiece with sharp corners and exceptional colour saturation; the princess cut is one of the most efficient cuts for maximising a stone’s vivid colour, and this ruby’s rose-red is known for its skin-brightening colour effect
• Solitaire setting — four prongs, no halo, no side stones; the solitaire format puts the ruby entirely centre stage and creates a ring that is immediately legible as a piece of genuine fine jewellery
• Diamond pavé band — round brilliant diamonds run along the top surface of the band, adding a continuous line of sparkle that frames the ruby from below without competing with it; the pavé detail elevates the band from plain to polished
• Timeless, versatile silhouette — the solitaire format works for every occasion, from daily wear to a formal event; a ring that pairs with everything and never goes out of style
• Guilt-free luxury — lab-grown rubies share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
