Very sophisticated imitation jewellery was made in Europe in the 18th century. It was sold by many of the leading jewellers. This style of earring (with three drops from a central top) is known as a girandole, and was very typical of the mid- to late 18th century. Before Australian opals became accessible, the opal was a rare stone. Here its shimmering beauty was achieved by setting a pink foil beneath a milky blue glass.
