Cleaved, water clear gypsum (variety selenite) hosts sparse iowaite (in small, turquoise crystals), less sparse magnetite (as tiny, magnetic octahedra) and sparse chondrodite (as one gemmy, orange crystal as well as orange masses). A previous dealer label indicates valleriite to be present; if it is, it is only present as microscopic grains. All of this sits on a rock matrix. This same dealer label also lists clinochlore instead of chondrodite but this is very likely an error. Iowaite - Mg₆Fe³⁺₂(OH)₁₆Cl₂·4H₂O and valleriite - (Fe²⁺,Cu)₄(Mg,Al)₃S₄(OH,O)₆ are both globally rare species, which (according to a previous collection label) form 'a unique association found in only a single pocket".
