Description
Description
A remarkable statement ring featuring a 17.14ct natural blue star sapphire originating from Sri Lanka (Ceylon).
Cut as an oval cabochon, the sapphire displays natural asterism—a captivating star that moves across the surface of the gemstone under direct light. The sapphire is completely untreated, with no indication of heating, preserving its natural colour and individual character.
The centre stone is bezel-set in 18K white gold and surrounded by a halo of natural round brilliant-cut diamonds. Further diamonds are set along the shoulders of the band, adding brilliance while keeping the impressive star sapphire as the principal focus.
This distinctive piece combines an important gemstone weight, natural asterism and classic diamond-set craftsmanship. It can be viewed by private appointment with Meralda Jewellery in Mayfair, London.
