Lab Ruby Oval Art Deco Double Square Halo Pendant Necklace | S925 Silver Baguette Bail

Deep red inside two squares of diamonds. A pendant that has always known it belongs somewhere important.

An oval-cut lab-grown ruby in vivid, deeply saturated red sits within a double-layer square diamond halo — an inner ring of round brilliant diamonds tracing the square outline of the pendant, and a second, larger outer ring of round brilliant diamonds creating a bold concentric frame with a deliberate gap between the two layers. A baguette-set diamond bail above connects the pendant to the chain, adding a clean rectangular diamond detail that gives the piece a jewellery-house finish from every angle. The double-square construction is unmistakably Art Deco in character: structured, geometric, and quietly extraordinary. At $202.50, this is the ruby pendant that earns its place as the centrepiece of any collection.

Why You'll Love It

• Double-layer square halo — two concentric square rings of round brilliant diamonds, separated by a deliberate gap, create a pendant with genuine architectural depth; the double-square construction is far more visually complex and interesting than a single halo, and the gap between layers adds a three-dimensional quality that catches light differently at every angle
• Art Deco geometric composition — the concentric square halos and oval ruby create a composition of pure geometric precision; the cut-corner square outline is a defining Art Deco design element that gives the pendant a structured, architectural quality associated with the great jewellery houses
• Baguette diamond bail — a baguette-set diamond in the bail above the pendant adds a clean rectangular sparkle at the chain connection; the bail is a considered design element in its own right, ensuring the pendant looks exceptional from every angle including when the chain is visible
• Oval ruby centrepiece — the elongated oval maximises the ruby’s vivid red colour and creates a warm, graceful focal point within the double square frame; the colour is known for its skin-brightening colour effect and sits beautifully within the all-white diamond surround
• Guilt-free luxury — lab-grown rubies share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
