What is Fluor-liddicoatite?
A rare member of the tourmaline group, fluor-liddicoatite is a brittle but very hard material categorized only in 1977. A prismatic crystal, fluor-liddicoatite often exhibits color zoning in which different sections may be darker, lighter or a different shade entirely. It is named for Richard Liddicoat, the gemologist who invented the GIA diamond-grading system.
