About Bismuth: Bismuth is number 83Bi on the periodic table of the Elements. Bismuth is rarely found in nature in its elemental form. Of growing interest are laboratory-grown bismuth crystals. Its color consists of iridescent metallic yellow, blue and green hues.

Of interest to hobbyists are the pseudo cubic \"hopper\" crystals that are always present on the laboratory produced specimens, they are not seen in but only the rarest of natural crystals. Hopper crystals are a unique crystallographic curiosity Just the edges extend outward from the center of the crystal leaving hollow stair step faces between these edges. The hopper crystals form due to the disparity of growth rates between the crystal edges and the crystal faces.

Note: Our photos are taken with a Panasonic DMC-TZ5 Lumix camera under halogen lighting (in most cases). We do our best to get a true representation of our stones. Sometimes because of enlar0ging the photo, or because of different settings on individual monitors there are variations in color.
