A sharp, gemmy, 1.3 cm, indigo-blue benitoite crystal beautifully attached to a lustrous, black neptunite crystal from the famous and now-closed Dallas Gem Mine. The bit of natrolite is a nice accent. The benitoite has textbook crystal form and sharp beveled edges. A CLASSIC Dallas Gem Mine thumbnail combo.
