Two-sided Italian blue Fluorite on a contrasting white Fluorite matrix with minor purple Fluorite. The transparent to translucent satin luster cubic crystals exhibit a classic two phase clear to white inner core with external cobalt blue phantoms. The largest crystals are up to 1.5 cm. The cubes do have a preferential white coating on some faces that appear to have be covered with a very thin late third phase of light purple Fluorite. Contacting is noted along the back and front edge.The crystals are in excellent condition. The blue hue varies depending on lighting but shows its most brilliant color under cool LED lights and purple fluorescence under UV lights. An cool double-sided specimen with a lot going on.
