It is an ancient method of decorating the metals. Granulated objects were found in jewels of Minoan Crete from 1800 BC, and in the tomb of Pharaoh Tutankhamun built in 1350 BC. This technique came to its peak by the Etruscans and the Greek goldsmiths from the 8th to the 2nd centuries BC. In the 18th century Europe was fashionable in the "Etruscan style" of jewels that resembled the jewels of Pompeii which were based on the technique of granulation.
To make a granulated gem, garnet welding is done on a metal surface. The grains are placed on the metal foil according to pre-designed motifs, or randomly. Today jewelry with a granular appearance is currently manufactured using the casting method for productivity reasons.
The gold ring with the exquisitely precision-decorated decoration was found in Prasos and is kept in the museum of Heraklion, dating back to 1200 BC.
