There's no need for broken diamond. Since diamond is indestructible, this would also be useless, although I like the sapphire suggestion.
If we make it, alot of saves will not work, but we can add it in a mod and call it "RMND" aka "Realistic Diamond" its disc can be: "Realistic Diamond, More realistic-like DMND that can be destroyed."

...Or Broken Diamond which could be a solid with tmp colour variation and realistic processes, along with destructibility.
"BDMD"
"Broken Diamond, destructible form of DMND."
