Ex Joan Lamond Collection. Acquired by Joan in 1996. Ex Museum Victoria. Width of view 11.5mm. Photos are white light, longwave ultraviolet and shortwave ultraviolet. Sellaite is cream to white and glows greenish under longwave, more cream to yellow under shortwave. It also looks like it is intermixed with muscovite mica. Fluorite is grey and purple. The purple area does not fluoresce under longwave, and only just under shortwave. The grey fluorite strongly fluoresces blue under longwave and is much more subdued under shortwave.
