A superb, water-clear (selenite) gypsum crystal cluster, featuring a large and well-formed central crystal adorned with a spray of small crystals near one termination. Fluorescent under both longwave UV (blacklight) and shortwave UV. Under the latter it displays 'hourglass' zoned fluorescence. From a locality famous for superb gypsum specimens, this example is in pristine condition. A must for any collection of gypsum or German material.
