Gypsum forms concretions of selenite blades called desert roses or sand roses, growing in sediments that are subjected to concentrated brines. The crystals grow from a central point, and the roses emerge when the matrix weathers away. These Desert Roses are a bit different than the typical ones seen because they are a deeper brown without any of the white edges that we see more often and have the sand they formed in included in them.
