Would it be possible to add a decorative 'Stable Chaos Crystal', either creative-only or craftable using Chaos Shards, for aesthetic purposes? I love how the crystal looks and sounds, and the fact that you cannot place them in creative for decoration purposes has been driving me a little nuts, since I have a really neat base build in mind using them. If this is possible, please have the decorative ones produce the cool sound that normal ones make too.

I mean the one that spawns in the center of Chaos Islands, which you mine after killing the Chaos Guardian, not the Endercrystal-like things.

There is already a way to spawn them creatively but remember they will still go boom if you break them.
