A striking, two-sided, large cabinet specimen of glassy and lustrous, light blue celestine blades with chisel terminations from an uncommon locality in Tunisia. The blades are coated with starkly contrasting, rust-red hematite and lightly dusted with calcite microcrystals. This piece was collected in 1998 by Dan Weinrich and Don Edwards from a giant walk-in vug. These were initially misidentified as baryte. An XRF analysis on a typical specimen found it to be fairly pure SrSO4. Ex. Dr. Ed David Collection.
