Me too Tom, thank you for digging them out!
The expanding one, even if it was made for production, never came on screen, doesn’t match anything made for production and the green crystal was weird since at the time before post editing the blade was blue.
And crystals powering lightsabers wasn't a thing until the EU, if I recall. The only crystal anything connected to STAR WARS by RotJ would be the Kyber crystal from Splinter's of the Mind's Eye and that was just a McGuffin "force crystal" (an abandoned concept from early Star Wars drafts) from that book.
