A BEAUTIFUL, mounded plate aesthetically covered with mirror-finish, jet-black neptunite crystals to 3.0 cm on super-contrasting, snow-white natrolite matrix from the famous and now-closed Dallas Gem Mine. The large neptunite is doubly terminated and the only neptunite crystal damage is along the periphery.
