A single Vivianite crystal on a pyrite base makes up this small thumbnail specimen. The Vivianite is in pristine condition, showing no damage of any sort, and has dimensions of 0.5 x 0.3 x 0.2" (1.3 x 0.8 x 0.5 cm). Its monoclinic prismatic form is likewise excellent, with very well-defined edges and clean, smooth faces that possess a bright pearly luster. Its color is a moderately dark forest green with a subtle hint of blue, and it is transparent and so clear as to be gem-quality, containing only 2 or 3 very small internal fractures. It rests on a thin crust made up of countless tiny (nearly microscopic) pyrite crystals that have a deep golden color that is tinged with a colorful iridescence and the standard metallic luster. I have placed it in a domed plastic thimble box for display and protection.
