OKF-183 Vivianite Siglo, Llallaqua, Bolivia. Ex. Nancy Collins collection. This is a very old specimen (not the new material from the past decade). The crystal measures 5.1 x 1.8 x 1 cm and is transparent. The color is a light grayish blue and a crystal form is rather complex and composed of two crystals and tight parallel growth with the larger of the two having a slight twist. This is not damage as there is no internal stress fracturing there would be evident if it was. The surfaces are glassy smooth and there is no damage whatsoever. A very desirable old-timer. $270
