Winter Survival by Maw (Settlements version) How do i get diamonds

[BobbahBrown]

This question has been bugging me and i cant find it.

Where the hell do you get diamonds from (Oh and also, bonus question What about crystals?) and how do you get them? (What tools?)

This has really been bugging me...

This is a gamemode variation called Winter Survival by The Maw. (Some people call it Settlements Version)
