Lab Sapphire Cushion Cut Marquise Diamond Half-Crown Pendant Necklace | S925 Silver Fan Spray

A deep blue cushion above a fan of white diamonds. The pendant that looks like a crown worn sideways.

A large cushion-cut lab-grown sapphire in vivid, deeply saturated royal blue sits in a four-prong setting above a five-stone marquise diamond fan — five marquise-cut diamonds arranged in a graduated half-crown formation below the sapphire: one larger marquise at the centre, flanked by two progressively smaller marquises on each side, their pointed tips radiating outward in a fan or spray silhouette. The marquise cut’s elongated, pointed silhouette creates a fan with a sharp, graphic quality that a round or oval stone arrangement cannot replicate; the five stones’ graduated scale gives the fan a natural, organic taper that reads as a half-flower or crown from a distance. The cushion sapphire’s deep royal blue and the marquise diamonds’ white brilliance create a two-tone composition of exceptional clarity and contrast. Suspended on a polished S925 silver cable chain. At $207, this is the sapphire pendant that earns its place as the most considered everyday piece in any collection.

Why You'll Love It

• Marquise diamond fan base — five marquise diamonds in a graduated half-crown arrangement create a base with a sharp, graphic quality that a round stone cluster cannot replicate; the pointed tips of the marquise cuts radiate outward in a fan silhouette that gives the pendant a sense of direction and movement
• Graduated scale composition — the five marquises step down in size from the centre outward, creating a natural, organic taper that reads as a half-flower or crown from a distance; the graduated scale gives the pendant a considered, jewellery-house finish that a uniform stone arrangement cannot achieve
• Cushion sapphire centrepiece — the cushion cut’s soft, rounded corners and deep pavilion maximise the sapphire’s vivid royal blue colour saturation; the large table facet allows the deep blue to be seen clearly from across a room, and the cushion’s antique character gives the pendant a timeless quality
• Blue and white contrast — the combination of vivid royal blue and white diamond brilliance is one of the most celebrated colour pairings in fine jewellery; the marquise fan’s white brilliance frames the sapphire from below and amplifies the stone’s colour by contrast
• Guilt-free luxury — lab-grown sapphires share the same optical and chemical properties as mined stones, with a significantly lower environmental footprint
