VAULT® 5.67 Carat TW Cushion Cut Brazilian Rubellite Tourmaline and 2.41 Carat TW Diamond Halo Ring in 18ct Yellow and White Gold

Showcasing the vibrant allure of a 5.67carat Brazilian rubellite tourmaline, this Vault® halo ring is masterfully crafted in 18ct white and yellow gold, a two-tone setting that amplifies the gemstone’s rich pinkish-red hue. A classic oval-cut diamond halo frames the centre stone with radiant precision, while tapered baguette diamonds and additional round brilliant-cut diamonds along the band introduce refined layers of light, enhancing the tourmaline’s natural brilliance without overwhelming its vivid colour.

Sourced from the famed Cruzeiro Mine in Minas Gerais—one of the world’s most prolific producers of tourmaline—this remarkable gemstone is a product of the powerful continental collisions that formed the ancient Gondwana supercontinent. Such geological origins contribute to the exceptional colour and clarity prized in fine rubellite. Notably, only around 10% of tourmaline production yields clean facet-grade material, with stones of significant size becoming increasingly rare.
