Social stratification and hierarchy is also evidenced through the variation in quantity and quality of grave goods associated with those of different social status. The elite East Tomb at Huaca Loro, contained over a ton of diverse grave goods, over two-thirds of which were objects of arsenical bronze, tumbaga (low-karat gold), silver and copper alloys, and high-karat gold alloys. Other grave goods of the elite included semi-precious stone objects, amber, feathers, textiles, imported shells (such as conus and spondylus), shell beads, and double spout bottles. (Nickle Arts Museum 2006, p. 87; Shimada 2000, p. 56; Bruhns 1994, p. 290) On the other hand, commoner burials had a significantly less amount of grave goods of different types, made of less valuable materials. For example, commoner grave goods at Huaca Loro were usually restricted to single-spout bottles, utilitarian plain and/or paddle decorated pottery, and copper-arsenic objects, instead of the precious metal objects of the elite tombs. (Nickle Arts Museum 2006, p. 87, Shimada et al. 2004) The power of the elite of Sicán society is demonstrated not only by the amount, quality, and diversity of exotic and status goods accumulated in the tombs, but also by the amount of time and labor that would have gone into making and acquiring them.
