Jewelers generally rely on something called a thermal-probe to detect a fake diamond. In 16th century Italy, hairstyles changed with hair being swept away from the face leaving ears exposed although for another 100 years things stayed the same in England, Spain and France with the wearing of high collars keeping earrings out of fashion. By the 17th century, earrings became very fashionable accessory for the well dressed lady across the whole of Europe.
