     In celebration of my 1998 mining project at the Junnila Property (located only 5 miles from the famous Benitoite Gem Mine), I have dedicated this page to the world-class fresnoite specimens I collected during that hard, but VERY fun summer!

     The pictured specimens represent a monument to this truly unique species. Fresnoite (Ba2TiSi2O8, Tetragonal) closest resembles in chemistry, and environment of formation, the better known and more famous species Benitoite (BaTiSi3O9, Hexagonal).  But, fresnoite is much more rare and less is known about it.  Like it's cousin benitoite, fresnoite also has a unique crystal form. Think of it as a 4-sided pyramid and the base, for a total of 5 faces, in its ideal crystal form.  More typical at the Junnila mine are those crystals that have the top of the pyramid cut off by another flat face, giving them a 6th face and tabular crystal form.  Until the Junnila fresnoites, this species was known only as micro grains, with rare crystals to 3mm.  Pink fresnoite was first observed at the Junnila mine.  When peachy-yellows combine with this pink, seen in some specimens from this mine, the results can be quite attractive, especially when on white analcime crystals.  This color combo is rarely seen in other minerals. Fresnoite is also highly fluorescent under SW-UV light (See my article for pix). For more scientific and locality information about fresnoite, see MINDAT.

     Since my 1998 heavy-equipment project, no more quality fresnoite has come from the Junnila mine (or anywhere else in the world for that matter). My discovery, to this day, remains the world's greatest for this rare and aesthetic species.

       Please feel free to read my article (published in Rock & Gem Magazine, March, 1999) and enjoy the specimens I have listed for sale!  If you have any requests for other fresnoite specimens that you do not see here, please write and let me know.  SCOTT
