Throughout subsequent centuries, the use of precious metals and gems were a constant among the most powerful and influential classes. Their use depended largely on fashions, which in turn responded to the availability of materials: for example, in the 16th century the use of pearls skyrocketed, even being included in outfits, sewn to dresses.

This demand continued during the following century, with the appearance of the brilliant cut, attributed to the Italian Peruzzi. However, other materials or techniques, such as enamel, glass or narwhal horn (which was believed to be a unicorn), have also been present in different historical periods. Manufacture of new materials used in jewelry In 1670 Londoner George Ravenscroft , owner of the Savory Glass House in London, discovered a method of producing lead oxide glass that had a much higher refractive index than other traditional materials, hard enough to be cut. A few decades later it was Georges-Frédéric Strass who found a new, harder crystal, known since then as strass . Imitation stones were also made in Venice and Bohemia, with a variety of colors depending on the added oxide. In addition, the use of pyrite and faceted rock crystal was introduced to imitate diamond . In the area of metals there were also novel advances.
The use of gold and silver was still exclusive to the wealthiest classes, so an English watchmaker named Christopher Pinchbeck developed a new alloy composed of 17% zinc and 83% copper, called . Its golden color emulated gold quite well, and was also valued for its price and malleability. This watch dates back to 1775 and is made with , the alloy created by Christopher Pinchbeck, which imitated gold.

Steelworkers, who had traditionally made swords and boxes, realized that steel, polished into facets, could have a metallic luster similar to that of pyrite. Although the origin of this type of work is in Tula (Russia), during the time of Catherine II, the most famous workshops were located in Woodstock , a small town on the outskirts of Oxford. Steel also began to become fashionable in France, so Monsieur , Marie Antoinette's jeweler, opened a store, in which the high prices he assigned to his genre caused the nobility to also become interested in this type of items.
