Garnet and Other Mineral Specimens from Marmora, Ontario For Sale


Typical Marmora, Ontario, Canada garnet mineral specimen. 


The working mine, Marmoraton Iron Mine, just south of town has produced nice mineral specimens for many years.  Dark colored garnets, epidote, calcite, quartz and other minerals are often encountered.  Very unusual are blades of magnetite.  To-date, field trips can still be arranged to this popular location.







OKK-138    Garnet on Epidote with Pyrite    Marmora, Ontario, Canada.  Collected by Michael Walter, circ. 1990.  The epidote coated matrix is a deep green color and flashy due to the micro crystallization on its entire surface.  The garnets are dodecahedrons to about .5 cm and scattered about.  They are a metallic brown color and some are coated by an overgrowth of an unknown mineral.  9 x 6.4 x 3.4 cm overall.  Almost all the pyrites are on the backside.  Stands on end for display… damage free.  Very nice.  $80








OKK-124     Garnet (Variety Andradite)    Marmora, Ontario, Canada.  Collected by Michael Walter. A thin specimen with a nice upper surface encrusted with opaque garnets.  7.2 x 2.3 x 2.2 cm overall.  Garnets have nice color and textbook form.  Some contacts but nothing with damage.  $30








OKH-328    Andradite    Marmora, Ontario, Canada.  Ex. Dr. Steve Chamberlain Collection.  An attractive 1.6 cm crystal in schist.  It sits high on the matrix and is damage free but does have a contact area on backside.  3.1 x 2.6 x 1.5 cm.  Nice.  20$. 







OKJ-547     Hematite on Quartz     Mamora, Ontario, Canada.  Self collected by Michael Walter, mid 1990s.  This was the nicest example of the type of material rarely found at this quarry.  I had it analyzed to verify species.  Small metallic fibrous balls to several mm each coat the bright quartz crystals. Domical so it views well from all sides.  Needs to be seen in hand to really appreciate.  3.5 x 2.3 x 1.7 cm.  Nice luster, great aesthetics.  This is one of those uncommon things found only through field collectors well versed with the given locality.  $95

OKF-695    Pyrite    Canada Talc Mine, Madoc, Ontario, Canada.  Ex. Dr. Steve Chamberlain collection.   This is an excellent specimen for the location and very interesting in several ways.  The piece measures 10 x 6.5 x 5.5 cm and sports large pyrites to 3.6 cm on edge.  The largest crystal is incomplete (contact with matrix or damage?) on its backside but this does not show in normal viewing.  The crystals have nice luster and very unusual growth features to their crystal surfaces.  The matrix is a dark brown schist which provides a nice contrast and the specimen has a flat base so it stands and displays well.  An excellent piece from an uncommon pyrite locality.  85$
