The high-purity 19.2k gold structure gives the piece a particularly rich and distinctive tone, which embraces the bright play-of-colour of the opal. Green, pink, yellow, and blue flashes spread across the surface with a luminous and balanced appearance. A champagne-coloured Mozambican tourmaline accent adds detail and warmth, complementing the refined proportions and colour palette of the piece. The back of the opal presents natural imperfections, visible in the images, which do not affect the overall visual performance of the stone. Opal colours arise from their interaction with light. Images aim to show the play-of-colour under different conditions.
