Honey calcite crystal nodules from Morocco. Shine a UV light on them, they'll glow a very bright white. They're also phosphorescent! Phosphorescence is what happens when the mineral still glows after the UV light source is removed. The video shows this in action.
We nicknamed these "cauliflower calcite" due to it's appearance and color under UV.
