An unusually fine and lustrous cluster of sharp, large, crystals of steenstrupine-(Ce) to 1cm from the noted Ilimaussaq alkaline complex in Greenland. Steenstrupine-(Ce) is a super complex sodium manganese iron cerium zirconium thorium silicate-phosphate hydrate! What an example of naturally occurring chemical chaos! This is a great cluster with well-formed crystals, exemplary for the species.
