Granulation (from Latin:granum=”grain”) is a goldsmith’s technique whereby the surface of a jewel is decorated with small spheres of precious metal (named granules), according to a design pattern.The technique is said to have originated in Sumeria (present day Iraq) as early as the third millennium B.C. Later, in the first millennium B.C., the technique was adopted by the Etruscans living in what is present day Italy. The ancient Greeks employed granulation work as well, but it was the craftsmen of Etruria who became famous for this technique due to their mysterious deployment of fine powder granulation without apparent use of hard solder.
