16" 3g 2mm necklace w/sparkly ball pendant

16” gold necklace with glittery ball pendant. T.w. 3g, and approx 2mm. I can’t tell if the stamp says 925 meaning it’s gold over sterling or 825 which is European for 19k gold & has been used in European jewelry. This is stamped Italy, so could apply. I’m pricing as if it’s gold over sterling, as I have no way of being Positive that it’s solid gold although it read gold with a cheap acid test from Amazon. Just not sure I trust that. I don’t want to mislead anyone & wud rather sell for less than charge more & be wrong, in case it isn’t 19k gold. If it is you get lucky. The stamp is in pics above, so you can decide yourself what you think it says, 825 or 925. Either way you get a beautiful, like new, vintage necklace that was never worn, at a good price, even if it’s gold over sterling. (Last pic is a makers mark but I don’t know who the designer is). PRICE FIRM Pet friendly/smoking home.
