Are they large enough to wear over top of eyeglasses

Depends on the size of your glasses. But they are a little weighty so they might fall forward a lot it they can't sit all the way up your nose if you block them with other glasses.

Will the gems on it fall?

I’ve had them for a while and they didn’t! They still look like new! It’s a bit heavy but they are beautiful

Will the diamond on it fall?

I’ve had these glasses for awhile and I have not had any fall off. They’re a really good quality!

My order is taking too long before i get ripped off and never get my order can i please get my money back? I don't want to wait longer

Products manufactured overseas takes much longer to deliver, once here in the US, the oder have to go through customs. Also, due to the global pandemic and supply ships backed up off the coast of California, hopefully, you'll get your order by Dec. 2021. If you go through Amazon customer service or your bank you should be able to get your money refunded.😎
