Real antiques or fake fakes

[Ego Me Orno]

Greetings everyone. I am new to this forum. I am almost 30 years young and have been buying vintage and antique jewellery for years now as I am an amateur antiques dealer. I only recently got into jewelery from antiquity. I am from Serbia (red flag, but at the same time we have a very rich earth in these antiques) and I hope to hear thoughts on some pieces I bought, whether they are genuine or fakes as I suspect. I appologize for the spam and too many photos, but I am compleyely lost, and the lack of reputable institutions in my country that are willing or have the knowledge to help does not exist. First ring is bronze, rest is silver. I will make a seperate post for 1 gold.
