This is a pair of Arkansas quartz crystal clusters.

CLUSTER - Clusters are points growing together on a matrix. Some Clusters grow on a sandstone matrix, others on all quartz, and still others may grow from a ‘seed’ of crystal (like a mass of double terminated points). Clusters are good for helping with group dynamics. Families, co-workers, anywhere a group of people might need help in getting along. They are also good for raising the vibrations in an environment and bringing light and energy into that space.
