welsbury re gold ornaments
As I understand the evolution/progression, neolithic societies eventually developed to the point that some individuals had more status than others, and wanted to show the elevated status. The initial status pieces were colored rocks (medicine pouches) progressing to figures and jewellery in various colors (Olmec bluish jade, Maya bright green jade, Mescala dark green serpentine, etc.).
Then came gold, which notwithstanding its common occurrence in some areas, had been ignored. What changed ? Technology arrived, imported or indigenous ? Hammering, annealing, soldering, casting, alloying, tempering, surface etching, etc.
The neolithic society started changing into its next progression 'The Bronze Age' using copper and its alloys.
With the advent of gold ornamentation jade abruptly deceased being the main part of high-status burials.
I am not so familiar with the many smaller groups in the US area; I know some utilized and traded turquoise, were green rocks preferred (to exclusion ?) by any groups?
I know of no groups having gold status ornaments - they would have been killed after torturing for info. Just like to the south.
