Antique necklace earring set Alaska black diamond and gold

Antique jewelry Necklace and clip on earring set Previous owner said it is at least 70 years old Alaska black diamond ( hematite ) , clear diamond looking stones and apparently gold (I was told real but I am no expert … I cannot find any stamps! So maybe filled or plated, I really can’t speak to this but it’s beautiful!) It is missing one stone!!! See pics Chain is beautiful and clasp works good. It is definitely an old set I just can’t speak to the authenticity without some kind of proof. Feel free to ask questions! Offers welcome, bundle with other items for a great deal! New to posh?
