Blue Diamond

Elton Morrow was a scientist exposed to fragments of an indestructible diamond, which bonded to his skin and granted him superhuman durability. Operating during World War II, he became the hero Blue Diamond and served alongside other Golden Age champions.

Born in the pages of Daring Mystery Comics #7 in 1941, Blue Diamond is a genuine Marvel Golden Age original, conjured by creator Ben Thompson during the era when superhero comics were still finding their footing. With a publishing history that stretches all the way to 2012 — a remarkable 71-year span — this character has proven far more durable than the average wartime adventurer, resurfacing across titles like Avengers / Invaders and Marvel Premiere long after most contemporaries faded into obscurity. The company Blue Diamond keeps is nothing short of legendary: sharing pages with Captain America, Bucky, Namor, and Steve Rogers places this character squarely within Marvel's most storied heroic tradition. Rare in appearances but rich in heritage, with a key issue to their name, Blue Diamond is exactly the kind of deep-cut discovery that makes Golden Age collecting so endlessly rewarding.
