Specimens of Fluorescent Chalcedony Nodules, collected from Morocco. This mineral belongs to the quartz family and is very similar to carnelian, even having a waxy lustre, although it tends to have a botryoidal crystal habit. These particular samples are fluorescent under shortwave UV light and display a bright orange/yellow colouration. They range from 1.5 – 2 inches approximately and come in a white card tray with an information label.
