Hopper crystals are the technical name for the basic crystalline structure of Bismuth. Though terms like "Tower" and "Gem' describe a nuanced physical form, they are all classified as hopper structures. These 3-dimensional cubes form pyramidal funnels (hoppers) toward the center of the crystal, giving them a unique, otherworldly geometry.

… The structure of a bismuth crystal is just so wild and the beautiful color that happens when it oxidizes is captivating. When metal oxidizes, it means that its outer layer has changed because of its exposure to the oxygen in the air around us. When iron oxidizes, it gets a red-orange colored layer we call rust.

The three most common basic crystal patterns are: Body-centered Cubic. In a body-centered cubic (BCC) arrangement of atoms, the unit cell consists of eight atoms at the corners of a cube and one atom at the body center of the cube. In a body-centered cubic arrangement, a unit cell contains (8 corner atoms × ⅛) + (1 center atom × 1) = 2 atoms.

Bismuth is a trigonal native element, it belongs to the arsenic group of semi-metals. Its crystals are growing as rhombohedra or flat hexagons in parallel groupings. One distinctive physical manifestation of bismuth crystals is their signature habit of growing in a spiral, stair-stepped pattern around a central axis.

Bismuth has a low melting point of 271°C (520°F). As bismuth solidifies, it expands to form crystals. Artificially grown bismuth crystals form a spiral staircase structure. This shape is due to the higher growth rate on the edges compared to the inside. Bismuth metal is naturally a white-silver metal with a reddish-pinkish hue.

Main uses Bismuth compounds account for about half the global production of bismuth. They are used in cosmetics; pigments; and a few pharmaceuticals, notably bismuth subsalicylate, used to treat diarrhea. [7] Bismuth's unusual propensity to expand as it solidifies is responsible for some of its uses, as in the casting of printing type. [7]
