Modern Yeh Ming Zhou (YMZ), the Night Glowing Pearl of Taoist mythology, can now be made using Fluorite and rare earth elements such as Lanthanum and Yttrium. Ancient YMZ is extremely rare, and nowadays is held closely by the previously ruling families in China. Historically, only the Emperor was allowed to have YMZ. The Buddhist and Taoist traditions have the same flaming stone symbol for the night glowing pearl. YMZ is prized for its protective and intuitive qualities.
