This layout is a true fine jewellery classic. The central 7mm x 5mm natural opal serves as a colorful focal point, showing shifting flashes of iridescence that are balanced and brightened by the classic fire of the 12 surrounding accent diamonds. Set in rich 9ct yellow gold, it makes an unforgettable anniversary ring or birthstone statement piece. What special care steps should I follow for natural opal jewelry? Natural opals are softer than other traditional gemstones and sensitive to severe hydration changes. To protect its structural integrity and play-of-colour, always remove the ring before washing hands, using hand sanitizers, swimming, or handling household chemicals. Clean gently using only a soft, dry microfibre cloth, avoiding ultrasonic cleaner basins entirely. How will my ring arrive, and can it be resized?

Because this is a solid 9ct gold piece with a standard smooth band, it can be easily adjusted a few sizes up or down by any qualified high-street jeweller.
