Solomon's Diamond
In Reality Z-25 31-H, Solomon’s Diamond was a large jewel belonging to the Koravi tribe. Physically, "Solomon"'s "Diamond" was a huge jewel, almost the size of a person's head, and, despite the name, it was not a diamond at all, but a large piece of quartz in a brilliant cut shape.

It was, in fact, the legendary Philosopher's Stone, able to heal any injury, prevent aging, and transmute lead into gold; indeed, (COMIC: Nula! Naked and Alone!) Kaza felt a strange aura from it which he compared to that of Nerlana's tiara. (COMIC: Nula! Naked and Alone!) According to legend, its history went back thousands of years to the “alchemists and levite priests of Israel”. Alexander the Great was said to have conquered conquered Persia to claim it from them; after his untimely death, it passed to Ptolemy of Egypt and remained with his descendants until Cleopatra, who had her handmaid take it up the Nile and “into the jungle” to hide it from Augustus.

It was stolen from the Koravi temple sometime around the Boer War; its whereabouts for the next century were undocumented until it resurfaced at a Boothby's auction in the late 20th century. Catherine Maxwell, an old friend of the Kovari, purchased it and, (COMIC: The Danger, the Diamond, and the Dowager) decades later, made up her mind to (COMIC: Nula! Naked and Alone!) return to Buranda to restore it to its proper owners. Attracted by the legend, the Skull intercepted her and stole it for himself. (COMIC: The Danger, the Diamond, and the Dowager)
