Inspired by this question, I've wondered how it would world look, if those diamond berries were real.
Let's assume in my fantasy world of XVII/XVIII IRL technology have one species of plant that have diamond berries, for whatever reason. Also let's assume its quite common almost everywhere, not like regular weed, but it's not strange to see them in normal forests. Your typical berry would be something in size of raspberry.
The question is: What could people of my world do with those diamond berries?
Bonus question: Would be there any animals that use to some advantage those diamonds?
