Classic sample of Franklinite with Willemite in fluorescent Albite.  Under shortwave UV, the Albite fluoreces a deep red, in stark contrast to the bright green crystalline Willemite.  Under normal light, we have a number of well crystallized slightly modified Franklinite crystals to 1.5cm. A very nice display sample in both UV and normal lighting.
