See our: parure jewelry.
A set of jewelled ornaments decorated en suite or made of the same variety of gemstone, and intended to be worn at the same time, such as a necklace, bracelets, brooch, and earrings (and sometimes an aigrette or sévigné). The modern term is sometimes a 'suite'. Less than a full set is called a 'demi-parure'. Such assemblages of jewelry became fashionable in the second half of the 16th century and were revived in the 19th century; they were made with diamonds for formal wear and other gemstones for daytime wear. Some were made of Berlin Iron jewelry.
