to clarify i have a necklace 300 yrs old or so I'm told it was found in Russia after tore a building down.it is made of some sort of hair and had 250g worth of gold coloured nuggets attached around it. i have melted 1 of the nuggets down and hammered it flat after grinding the surface off and buffing on the wheel it smooths out and shines really good put next to a 9ct brace and looks and feels exactly the same is heavy to hold i didn't think was gold till melted down and shined is there any way to be sure that there is no gold in it machine says 240 where 540 means 9ct on my model of acid tester would 240 mean 4 ct or does it not work like that. just looking of a way to know as man is adamant it contains gold just made along time ago.and to recap its non magnetic same appearance as 9ct when buffed scratches with a knife and after heating melted at 1300 heated to 1580 then let cool and hammered flat. what other things could i try willing to buy sum equipment as gold in shop is taking off and really wont to get into it.is there a chemical that only reacts with gold or heating with something else?? really appreciate any suggestions or help on the matter guys thanks
