A fine specimen from the Dallas Gem Mine of California. Lustrous, partially gemmy, indigo-blue benitoite crystals to 1.2 cm richly cover the snow-white natrolite covered matrix on this piece. A sharp, highly lustrous, 1.3 cm neptunite crystal on the edge of the specimen is a very nice accent. Very fine, older material.
