History: After the discovery of the opal'd structure, which consists of nano-scale spheres, scientists sought to replicate its beauty in the lab. In 1974 , Pierre Gilson, who was responsible for introducing other synthetic gemstones such as turquoise and lapis lazuli, began to market synthetic opal. This particular example uses genuine abalone, with a coating, which gives the appearance of a black opal. 

Silver was first found in large amounts around 5000 BC, when prehistoric people dug the first copper mines. ... Large-scale silver mining had developed in Anatolia by 3000 BC. This was to meet the demand from the first ancient city states, which used the metal as a common medium of exchange.

The sterling alloy originated in continental Europe and was being used for commerce as early as the 12th century in the area that is now northern Germany. A piece of sterling silver dating from Henry II's reign was used as a standard in the Trial of the Pyx until it was deposited at the Royal Mint in 1843.
