My brother unfortunately passed away last week. She wasn't really wealthy but man was he addicted to buying second hand jewelry!
While going through his stuff, my husband found this necklace. It weighs approx 50-70 grams and he 'claimed it for us' (we basically share everything so what he owns is mine and vice versa). I don't really care about money but I do want to know if it's worth anything. It says 18K so I assume it's real gold? I do see it has some black around it so I'm not sure.
Honestly I just want to make sure we aren't robbing our sister and nephew by taking this jewellery like it's only worth 10 bucks if it's worth more.
Does anyone know if this is gold, silver or anything of worth? Does the symbol automatically mean gold? Are there a lot of fakes around?
Thanks!
