Silver Turquoise Necklace & Earring Set

This came from a coffee producer in South America and was auctioned for money to support women in 3rd world countries that work in the industry providing medical care. I don’t have much other info on this. There is an imprint of 9 something but can’t fully make it out. It’s a beautiful set, substantial and not hollow as far as I can tell. Inlaid with turquoise.
