A brand-new, unused, certified natural diamond and blue sapphire oval-shaped cluster ring, set in platinum and centred with an impressive 4.28ct oval-cut blue sapphire. The centre stone displays rich, saturated blue tones with elegant, elongated proportions, creating striking finger coverage and refined symmetry. Its substantial carat weight ensures a commanding presence, while the smooth oval outline enhances the depth of colour and the overall balance of the design.
Surrounding the sapphire is a double halo of brilliant-cut natural diamonds, extending seamlessly onto the shoulders and totalling 1.67ct. Graded F–G colour and VS clarity, the diamonds offer bright, near-colourless brilliance with excellent transparency, intensifying the vivid blue centre through crisp contrast and exceptional light performance. The platinum setting provides enduring strength and a clean, naturally white frame that elevates the stones' purity and radiance.
Natural blue sapphires of significant size are increasingly scarce, particularly when paired with high-grade natural diamonds. Strong global demand for vivid sapphires and certified diamonds continues to support long-term appreciation. Combining substantial gemstone weight, superior diamond grading, and timeless double-halo styling, this ring offers both remarkable visual impact and compelling investment potential in fine natural gemstones.
This lot includes the Gemologist Report/Valuation, a Presentation box, and a gift bag.
