Jumillaite is not a recognized mineral species. It's a post-volcanic mixture of different silicates, such as analcime, leucite and others. It's the white fluorescence of this material that enhances the orange-pink fluorescence of the apatite crystal. The fluorescence is caused by different rare earth elements.
