Prehnite is a calcium alunminum silicate; it is one of the first species named after an individual (Hoffmann, 1789). Back in the 1970s and 1980s, Jewel Tunnel Imports brought this material to the American mineral market. This example consists of solid replacements, in contrast to the hollow channels often seen. Part of the Charles Trantham (1936-2020) estate.
