A beautiful, excellent example of this strontium sulphate mineral. It is a large, thick tabular, singly terminated, light blue crystal with multiple terminations as I have tried to show in the close-up photo. A couple of bits of limestone matrix attached and contacted on the back where it was attached. Really nice, heavy crystal!
