This is a granular mass of pale green willemite, black franklinite, and red zincite crystals. It contains about 50% willemite, 40% franklinite, and 10% or less of zincite. Under a UV lamp, the willemite glows an intense green, making this an excellent fluorescent specimen. The image was taken under a short-wave ultraviolet lamp.
