I really don’t wanna waste money to get diamonds surely there is another way to get them
Hey Nyabrown 
Tales will (and already did) offer opportunities to win and gain gems without having to buy them 
I just can’t tell you when exactly 
However, as an author that would earn money when readers spend gems on their stories 
it kinda hurts to think it’s a waste of money
As far as i know, none of the stories require you to spend gems. They usually just offer additional content
