18ct White Gold Oval Cabuchon Star Sapphire with Bezel Set Diamond

18ct White Gold Star Sapphire & Diamond Necklace

A distinctive 18ct white gold necklace centred with an oval cabochon star sapphire, suspended beneath a single bezel-set round brilliant-cut diamond.

The sapphire measures approximately 12 × 10mm and displays the shifting star-like reflection characteristic of asteriated sapphires. This natural optical effect moves across the domed surface beneath direct light, giving the stone an appearance that changes with every movement.

Above, the round brilliant-cut diamond measures approximately 5mm in diameter, giving an estimated weight of 0.45–0.50ct, subject to its depth and proportions. Its clean bezel setting provides a crisp point of brilliance against the softer blue-grey character of the sapphire.

The pendant is suspended from a fine 1mm 18ct white gold curb chain, keeping the design understated and allowing the unusual sapphire to remain the focus.
