Purple Alum


Made in Poland.

These lab grown large Purple Alum crystals are a great choice for anyone who enjoys rocks or appreciates crystal structures. Grown on a host rock.



These large purple alum crystals are lab grown in Poland. Alum is a top choice for growing crystals because the pattern in which it crystallizes is very regular, resulting in an octahedron with a rich deep color. In other applications, alum is used for tanning leathers, cosmetics, and styptic powders. Although these specimens are made artificially, their gemmy color and defined crystals make it a worthy addition to any collection. Approximate dimensions: 2″ x 2.5″ x 1.5″

*Note– Each crystal specimen will vary slightly.
