What are online payment options with no chargeback protection?
Generally there's no ultimate protection against charge backs. Some methods are easier to charge back and some harder, and there's always the resort of going to courts. The hardest to contest is, of course, a cash payment or wire transfer. You need to remember that imposing unnecessary/unreasonable difficulties on your customers will drive business away. I can buy diamonds in the nearest mall with my credit card - why would I buy from you if you want cash, BTC, or any other shady way to pay? I'm pretty sure that whatever that is you're selling, anyone can buy elsewhere as well.
