Superbly perched atop on matrix of white Natrolite is a fine crystal of lustrous and translucent, rich blue Benitoite, measuring 2 cm in length. Also perched on the Natrolite matrix are slender black crystals of Neptunite, to 5 mm in length. It is not the biggest Benitoite, but it is among the finest for perfect frontal symmetry on display, that you can ask for and in a competitive miniature collection, that first look matters most.
