Teaspoon STILO DEMITASSE SPOONS (BRAZIL)

6 demitasse spoons each with a different Natural Gemstone at the end of the twisted handle.In original that states "From Brazil with Love" on it's sticker on the front and on the back sticker it says "Stilo CGC 62 540 208/0001-50 INDUSTRIA BRASILEIRA".I think these are from the 1960s. Each spoon is about 3.5" long. I cannot truly identify what metal these are made of, but I assume it is a sort of stainless metal due to the lack of tarnish on these.All are in lovely condition.These have never been used
