Ancient Peruvian Sicán earpiece

I had the luck of going to the Sicán museum in Ferreñafe in northern Perú. Quite inspiring to see all those ancient techniques applied to pottery, metallurgy and goldsmithing. This tutorial will be a consequence of the visit, and we will make a gold Sicán earpiece, based on one of the pieces seen in the museum. The modeling work is simple and the texturing, simpler still. There is an optional tweaking phase that can be a bit laborious, but it is optional.
