Indeed. Chests give random items. There is no telling whether it will be worth the gems you spend on opening it. In my opinion, the best use of gems is to buy and upgrade perks and special moves from shops, or to convert them to coins in case you're slightly short for an item you need to buy.

Never waste them to buy or upgrade ranged weapons, but you can use them if you get an armor or weapon you really, really like in store. And of course, never use them to open chests.
