I recently read your article on the name "Maboroshi no Ginzuishou" and it's translation as "Phantom Silver Crystal"…
Whilst I did note that you mentioned that the crystal doesn't necessarily need to be a "phantom crystal" (maboroshi no suishou) to take the name, I matched something earlier in your article with a post on a forum I read recently…
At the start of your article you mention that:
A phantom crystal “occurs where the growing environment of the gemstone changes and there is a color change or some other shift in the crystal that makes the crystal faces of the younger crystal visible INSIDE the present crystal”
Well, this forum post,
http://www.sailormoon.ws/forum/viewtopic.php?t=874, looks at the nature of Sailormoon's crystal, and the constant change in colour related to it, be it from usage, or position (inside or outside her brooch)…
Even though we cannot guarantee that it is a direct link, as we know Takeuchi-san didn't have all that much say in the creation and direction of the anime series, I thought it might have some sort of link, maybe the anime creators took the idea of the colour change…
