I wonder if my grandmother's jewelry is real

They all have their pair my grandmother I want to know how old they are who made them if they’re real and what’s worth and what are they

The best thing is to go to your local jewellery shop and have it tested. Sometimes I have paid a small fee to reimburse the jeweller for his time. I have good experience doing it. This way you can be absolutely sure. All the best, Michaela
