I suggest to create a separate article to Materioptikon; You can read Justice League of America #19 and You will see it seems more a machine than a Ruby; in Post-Crisis, the mystical Dreamstone empower the Materioptikon, but it was technological in Pre-Crisis. Then the first appearance of Dreamstone could be Sandman Vol. 2 #1.
