I found one similar to yours years ago - 925 with real diamond
many used to say "they don't put real diamonds in silver"
yes they do - usually small or chips but they do
Ive met people over the years that have said they had relatives that are allergic to gold and had all their diamonds
and other precious stones put into put into silver - wit price of gold still high
a lot more companies are putting real diamonds in almost anything - they put them in tungsten bands now - so always
worth a check
