Sardonyx cameo.The Renaissance and exploration both had significant impacts on the development of jewellery in Europe. By the 17th century, increasing exploration and trade lead to increased availability of a wide variety of gemstones as well as exposure to the art of other cultures. Whereas prior to this the working of gold and precious metal had been at the forefront of jewellery, this period saw increasing dominance of gemstones and their settings. A fascinating example of this is the Cheapside Hoard, the stock of a jeweller hidden in London England during the Commonwealth period and not found again until 1912. It contained Colombian emerald, topaz, amazonite from Brazil, spinel, iolite, and chrysoberyl from Sri Lanka, ruby from India, Afghani lapis lazuli, Persian turquoise, Red Sea peridot, as well as Bohemian and Hungarian opal, garnet, and amethyst. Large stones were frequently set in box-bezels on enamelled rings.[24] Notable among merchants of the period was Jean-Baptiste Tavernier, who in the 1660s brought the precursor stone of the Hope Diamond to France.
