The Stone of Jordan is a legendary ring with a dark, polished stone set in a thick, ornate band. The stone is deep black with faint, swirling red veins that seem to pulse subtly, suggesting its demonic origins. The band is made of a heavy, dark metal, possibly iron or obsidian, with intricate engravings of ancient runes and symbols that glow faintly when activated. The ring has a substantial presence, with a wide band that tapers slightly towards the stone, giving it a bold and powerful appearance.
