- Fluorite on Barite

A thick slab of white limestone is the matrix for flattened sprays of glassy and gemmy, colorless barite crystals to 1 cm across. Scattered on the barite are glassy and gemmy, limpid, light sky blue crystals of fluorite to 1.2 cm across. The combination of divergent forms and colors is outstanding and unusual. It is, though, very sparkly and bright - better in person! Mined June 1994 and from the Ross Lillie collection. RCL#1486.
