About Liddicoatite
Liddicoatite is a calcium lithium aluminum tourmaline, prized for exceptional color zoning that produces spectacular cross-sectional patterns of pink, green, red, and blue in triangular or prismatic forms when cut perpendicular to the c-axis. It was formally described in 1977 from Madagascar and named in honor of gemologist Richard T. Liddicoat. The most spectacular "watermelon" and polychrome liddicoatite cross-sections from Anjanabonoina, Madagascar, are among the most visually stunning collector specimens in tourmaline mineralogy.
