An AESTHETIC and EXCELLENT Dallas Gem Mine CABINET plate with partially gemmy, light indigo-blue benitoite crystals to 1.5 cm RICHLY sprinkled on natrollite-covered matrix. Scattered black neptunite crystals to 7 mm are a nice compliment. This is FINE, older material, HARD to obtain now with the closing of the mine.
