Pink pearly cleavage crystals in matrix to over 1cm. Baratovite is a rare mineral that occurs as a accessory in quartz-albite-aegirine veinlets, and fine-grained in aegirine syenites in association with miserite and ekanite etc. It is a rare lithium-titanium silicate with some non-essential zirconium. Three localities thus far worldwide.

The specimen represents a good example of mineralized Quartz veining with open spaces. The Quartz crystals have grown inward, perpendicular to the walls of the vein. The vein is mineralized with phosphate, in this case Baricite, a Mn-Fe phosphate. Baricite was first found at this locality and has since been found in only another four localities worldwide. It is the magnesium analog of Vivianite. The Baricite in this specimen is a metallic blue with lamellar crystals to 2.5cm.
