I made this with geometry nodes so it's procedural (not completely bc I modeled the crystals). Click on the distributed crystals and in the modifier tab you can adjust the them.
If you want to add them to your own object add a geometry node modifier to your custom object and select the 'Crystals' from the drop down menu.
