22K Gold Crescent Pendant.
Made Using an Ancient technique called Granulation.
Granulation is a very sensitive technique used in ancient civilizations.
Each granule is made by hand then placed very carefully over the metal sheet, the gold sheet is then heated to a certain temperature so that it melts and fuses to the tiny gold granules, if you over melt the gold the whole piece will melt and if you under melt it there'll be no fusion between the gold sheet and the gold granules.
Granulation is a technique sensitive process and takes years to master, and its only done these days by very few goldsmiths.
Next time you visit a museum look at the ancient Egyptian or Greek pieces and you'll be able to spot the granulation technique.
