filigree bracelet 835 mark

[tinasowders]

Hi, I have a bracelet that weighs 40grams filigree...its marked 835 that's it..no oval around the mark or anykind of shape or letter.....just 835. I was told this bracelet could be 20k gold so I had it scratch acid tested for gold using 14k acid...it failed...so then I had it tested for silver...it failed...so then I had it tested for platinum...it withstood the platinum acid perfect for about 30 seconds then disappeared. Low grade antique platinum not pure enuff for modern day platinum acid? I need some advice on this bracelet has anybody else had this happpen? What is the 835 mark really? some people say possible 20k gold.. People say low grade silver....I think people say low grade silver bc it does not hold up to silver testing...it tested worst than my 800 silver piece bc this 835 bracelet is not silver. I can not see someone handmaking this bracelet out of garbage...how do u test antique platinum without damaging it? Any advice or comments or knowledge about my post?
Thanks

Hi Tina,

Welcome to the forum.

Modern jewellery made out of platinum, the platinum is mostly pure and not mixed with other elements or metals and mostly of minimum 950/1000 fineness. So your acid could be to strong for an alloy of low grade platinum. I advise you to have your bracelet tested by an official assay office.
