Yeah, here I have to side with Rarity. This wasn’t meant to be a treasure hunt – that was a whim that popped into Rainbow’s head out of the blue, not something they agreed on – and she did just cause Rarity to both lose valuable resources and the time and effort she put into gathering those gems.
Dash crashed into the cart, so maybe that impact shattered the gems/diamonds/shiny-thingys instead.
Two words: Hammer time!
that scene in “Flushed Away” where he shattered the “Queen’s” gem to prove it was fake? That’s what this made me think of.
yes, but a good whack with a hammer is a whole lot more force than just falling on the ground.

RL gemstones aren’t really more durable. A good whack with a hammer shatters any diamond.
