Can crystals be used in a tank

Could I use big pieces of quartz crystal like instead of rocks? Just sitting here on ebay and I saw these crystals like in the pic below and thought about just them in the sand and using only floating plants.

I would worry that one of my fish opens himself with the tip of the crystal...

Make sure as well they are pure quartz and do not have metallic seems in them.

Some quartz can contain small iron seems, run a magnet along them to check.

It would also be slightly concerned at the sharp point but other than that they are totally fine to use.

10g Fry / Hospital / QT tank (as needed)

75g Saltwater Reef, Ocellaris Clownfish, Lyretail Antias (baby), Lemon damsel, Longtail Fairy Wrasse, purple dottyback, snails, crabs and a few LPS corals.

220g Still sitting empty (come on Lottery I need the numbers to come up!)
