Purple Sapphire and Diamond Cluster Ring in Platinum

The sapphire is secured in an elegant rubover setting, surrounded by a sparkling diamond halo with additional diamonds adorning the shoulders. Crafted entirely in polished 950 platinum, the ring features 0.35ct of F-colour, VS-clarity diamonds, including a delicate diamond accent positioned on either side beneath the central cluster.

Purple sapphires are among the most intriguing varieties of corundum, a mineral composed of aluminium oxide (Al₂O₃). While blue sapphire is the most widely recognised variety, corundum occurs in a remarkable spectrum of colours, including pink, yellow, green, orange and violet. Purple sapphires owe their distinctive colouring primarily to trace elements such as chromium and iron, which influence how light is absorbed within the crystal.

The cushion cut is especially well suited to coloured gemstones. Combining softly rounded corners with a broad faceted surface, it can enhance the perception of colour while maintaining an attractive balance of brilliance and depth. In darker purple sapphires, careful cutting is particularly important to allow light to travel through the stone without creating an excessively dark appearance.
