Savage Sword of Conan Vol 1 #230 Story Splash Page 4 Red Sonja Original Art (Marvel, 1995).

Gem I missed at the time and was lucky to find in the gallery of a true friend, thank you Kirk 't was real nice to see you again in NY!

Probably from the The Ring of Ikribu story by Roy Thomas (1981). The Ring of Ikribu is a powerful gem that can crush or create kingdoms. A powerful sorcer named Astoth is pursuing the ring in hopes of ruling a portion of the Hyborian kingdoms. His search for divine power brings him to the city of Suthad.

So so much in love with Tom's Art, lines,....! Would LOVE to add one of his old Sci-Fi beauties!
