Paula says - "In my opinion, this barrette shows all the design characteristics and workmanship of being Native American made. But because there is no hallmark that we can attribute to a specific artist we can't legally sell it as Native American made - read more."
What is repousse?
A method of forming a pattern on metal by stamping, hammering or pressing a design from the back to produce a three-dimensional bas-relief surface on the front.
100% solid silver won't tarnish but it is too soft to use for making jewelry - it could easily be scratched, dented and bent. Sterling silver has a small amount of one or more other metals usually copper, added to the silver. To be called sterling silver, the alloy must contain at least 92.5% pure silver. Sterling silver alloy is harder than pure silver but the added metals also can cause discoloration or tarnish.
The US Department of the Interior Indian Arts and Crafts Act of 1990 and its recent Amendments require that items described as Native American or Indian be made by an enrolled member of a federally recognized tribe. Furthermore, government regulations suggest that all attributions include the Native American Indian's name, tribe and federal tribal enrollment number. Because it is impossible to identify the artist for many vintage items, even if they are authentic Indian made items, we cannot and will not use the words Native American or Indian in association with such pieces.
