Shop question

Id like to clarify if the items on the shop that have gems and yellow shards on them cost both items or if its a “OR” condition.
Does any of the 2 buy the item ? Or must i have both ?
Kind of easy to test but i dont want to risk loosing the gems i got when i started playing.

It’s “OR”, not “AND”. When you click on that item you have a choice (two separate buttons) what you want to spend.
