A great example of bultfonteinite on some tobermorite group mineral, I've heard the name plombierite tossed around, but with these rare fuzzy things I'm never entirely sure-- and in places like this, the exact compositions can vary from specimen to specimen. What I can say however, is that these are exceptional examples of bultfonteinite-- in the past, I had only seen the mineral present as a fuzzy looking background accessory on some of the poldervaartite/ olmiite specimens from South Africa. On these specimens however, the bultfonteinite is definitely the focus, with solid botryoids of the mineral on a nicely contrasting matrix (of another fuzzy mineral that may one day also get its turn in the limelight).
This find was made around mid 2021.
