The two large octahedral alum crystals on this piece are up to 2" across, and are gemmy and highly skeletalized, a characteristic of crystals which grow quickly. The color on this lab-grown specimen is a lovely green, which contrasts nicely with the black matrix.  The luster is very glassy and shiny. Lab grown, so no damage.
