Chabazite vs Stellerite

Chabazite is a zeolite mineral that usually occurs as clear, white, pink, or pale-colored crystals in cavities of volcanic rocks. Its crystals commonly have rhombohedral forms that can appear pseudo-cubic, and its structure contains channels capable of holding exchangeable ions and water. Those properties make chabazite relevant to mineral collectors and to technical uses involving ion exchange, a...

Stellerite is a calcium-rich zeolite mineral in the stilbite group. It commonly forms tabular crystals or distinctive bow-tie and sheaf-like aggregates, often in cavities within basalt and other volcanic rocks. The mineral is named after Georg Wilhelm Steller, a German naturalist. Its pale white, pink, or related colors and crystal shapes make it a specimen mineral collected for study and display...
