VAULT® 21.91 Carat Cushion Cut Blue Cambodian Zircon and 2.16 Carat Round Brilliant Cut Diamond Halo Ring in 18ct White Gold

Brilliant and intensely luminous, this Vault® halo ring centres a remarkable 21.91 ct cushion-cut blue zircon, its vivid azure hue enhanced by the polished 18ct white gold setting. Surrounding the centre stone, eighteen round brilliant-cut diamonds introduce a refined sparkle that accentuates the zircon’s natural fire and clarity, creating a harmonious balance of colour and brilliance.

Zircon is celebrated not only for its beauty but also for its extraordinary scientific significance. Thanks to its unique ability to trap radioactive elements, zircon can track the passage of geological time—an attribute that allowed scientists to date the Earth itself to approximately 4.5 billion years, based on a specimen from the Jack Hills in Western Australia.
