An EXCELLENT specimen of LARGE, to 2.1 cm, partially gemmy, indigo-blue benitoite crystals aesthetically sprinkled on natrolite-covered matrix. This is FINE, older material, HARD to obtain now with the closing of the mine. Ed Ruggiero purchased this showy, pristine piece from Jo Runner at the Denver Show in June, 1975.
