A plate of botryoidal to stalactictic prehnite crystals rise from the flat surface, this comes from Mullaley, NSW. Like a lot of this material the color varies according to the light source. This goes from almost colorless thru pale yellow to a pale green in light. A decent three dimensional plate in good condition. I wish I could say these classic old prehnite specimens have some luster, but no, luster is not what they are known for! Ex Norman and Jocine Robinson collection. Large size.
