Cabouchon Jewellery was a high end Costume Jewellery Company, the Cabouchon jewellery range has been worn by several high society and famous ladies including: Princess Diana, Claudia Schiffer, Jerry Hall, and Marie Helvin. All Cabouchon costume jewellery is triple plated with either 18ct gold, silver or rhodium. Rhodium belongs to the group of platinum metals and is more durable and precious than silver. Each piece is first plated with copper to give the smooth final finish, followed by a plating of palladium, which seals the copper from the gold and ensures the gold does not discolour. The third plating is a hardened gold up to 3 microns thick which gives extended wear life to the finished pieces. Flawless full lead Austrian crystals and cubic zirconias are used in items with stones. For jewellery pieces which have enamel, the enamel is of the highest quality. Buff occasionally with a soft cloth to maintain the original shine. These classic yet contemporary pieces talk of the past and whisper of the future. Cabouchon offers an extensive range of high quality fashion jewellery and accessories. The whole jewellery range is nickel allergy free with the exception of some brooches and cufflinks. They are either classical or just fun and blend beautifully with real jewellery. They appeal to both men and women of all ages and fashion tastes.
