I'm seeing all these answered asks about Euclase being a half clear gem, and about those being taken away more, and I also just remembered that they used to be partners with Lapis Lazuli (right?) and so... What if that's how Lapis lost their body? Because the Lunarians were targeting Euclase, but Lapis protected them/got taken away instead?
euc and lapis being partners is just a fantheory, maybe even just an hc more than a theory
that being said, I like your hc and now I almost want to write it
