Living Diamond

A villain cut from the Silver Age's most gleaming cloth, Living Diamond made their mark in the pages of The X-Men #42 in 1968, conjured by the legendary Roy Thomas and Don Heck. This Marvel menace shares their earliest adventures with the likes of Professor X, Scott Summers, and the original X-Men lineup — rarified company that signals just how early and deep into mutant history this character reaches. With appearances catalogued across an impressive span stretching all the way to 2011, Living Diamond may be a rare find in the longbox, but their place in Marvel's Silver Age tapestry — immortalized in Marvel Masterworks — makes every appearance a genuine collector's gem.
