Boracite with Hilgardite and un-named new specie (Ref: 23.1-330-(D5598))
Boulby Mine, Loftus, North Yorkshire, England
64mm x 46mm x 38mm
A sparkling small cabinet specimen of Boracite in both mint-green and colorless crystals. Ex University of Delaware Mineral Museum, obtained by them from the Scott Williams collection. Along with the Boracite, the front is scattered with small Hilgardite crystals and the back is almost all Hilgardite. The Scott Williams label notes this was collected on September 1993, and this contains a new, yet to be named, specie, a white Borate mineral. We do not know for certain what that specie is or was at that time but suspect it is the new polytype Hilgardite 3Tc. From the modern classic locality of the Boulby Mine, (England) this is an undamaged and very attractive piece.From: Well-Arranged Molecules
