This custom museum display showcases an Authentic Bismuth Crystal, the longest known half-life of any radioisotope - the universe is about 1.38×1010 years old (time from the big bang to the present), the half-life of bismuth (the only naturally-occurring isotope) is approximately a billion (10^9) times the age of the universe.
Bismuth is a brittle metal with a white, silver-pink hue, often with an iridescent oxide tarnish showing many colors from yellow to blue. The spiral, stair-stepped structure of bismuth crystals is the result of a higher growth rate around the outside edges than on the inside edges. The variations in the thickness of the oxide layer that forms on the surface of the crystal cause different wavelengths of light to interfere upon reflection, thus displaying a rainbow of colors.No other metal is verified to be more naturally diamagnetic (materials that are repelled by a magnetic field) than bismuth. Of any metal, it has one of the lowest values of thermal conductivity and the highest Hall coefficient (The ratio of the induced electric field to the product of the current density and the applied magnetic field).It has a high electrical resistivity. When deposited in sufficiently thin layers on a substrate, bismuth is a semiconductor, despite being a post-transition metal.
Bismuth is also an ingredient in some pharmaceuticals due to its beneficial gastro-intestinal properties - it is the active ingredient in "Pink Bismuth" preparations such as Pepto-Bismol and Kaopectate. "Milk of bismuth" (an aqueous suspension of bismuth hydroxide and bismuth subcarbonate) was marketed as an alimentary cure-all in the early 20th century given its medicinal properties for a number of ailments such as bacteria causing peptic ulcers, treating eye infections, treating syphilis.
Since Ancient Egyptian times, Bismuth has been used in cosmetics, as a pigment in paint for eye shadows, hair sprays and nail polishes.
