A showy and beautiful plate richly covered with gemmy, indigo-blue benitoite crystals and lustrous, black neptunite crystals - all on a contrasting matrix covered with snow-white natrolite from the famous and now-closed Dallas Gem Mine of California. Some minor damage on periphery, but overall in good shape and with super gemmy crystals! The large neptunite is 1.3 cm. There is little likelihood of more material from this famous locality. Ex. James Zigras Collection.
