Silver bracelet in a Diaguita design including lapis lazuli and carnelian stones newest

Silver (.950 Britannia) standard made with lapis lazuli and carnelian inserts to a design typical of the Diaguita people of the Andes of Chile andNorth Western Argentina. It is quite unusual as it depicts only female characters. They are depicted between 3 stars and bounded by turquoise and carnelian triangles. I am unable to date with any accuracy but it has some age so I am guessing its probably 1960s or 70s although similar are still being made today newest.
