A translucent coating of hyalite opal lends the crystalline aggregates a distinctive glassy luster and displays vivid green fluorescence under ultraviolet illumination, creating a striking contrast with the underlying matrix. Kidwellite is a hydrated sodium-iron phosphate that develops as a secondary mineral in phosphate-bearing environments, while hyalite is a transparent to translucent variety of opal composed of hydrated silica.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eArkansas is noted for its diverse secondary phosphate mineral assemblages, particularly in the Ouachita Mountains region.
