Art Deco, Platinum, Cabochon Sri Lankan Sapphire and Diamond Ring

Product SKU: ARB-430

Sapphire and Diamond Ring. ‘Cabochon’ is the name for a domed cut, and apart from free-form tumbled beads, it is historically the oldest stone cut. Cabochons don’t rely on facets to sparkle and reflect light - rather, they rely on the stone’s colour and clarity to pool light within the stone, giving them a softer, more subtle appearance than faceted stones. This cabochon is extraordinary for its depth, which gives the stone a beautiful interior play of light, shifting with the angle of the stone. Sri Lankan sapphires are the perfect choice for this historic cut, with the relative lightness of their famed ‘cornflower’ blue allowing light to shine beautifully through the stone without being obscured. This beguiling sapphire is set within a delicate quatrefoil setting set with rose diamonds - a simple and poetic touch.
