New Jersey area is probably the most famous location for fluorescent minerals. The mines of Franklin and the Sterling Hill Mine at Ogdensburg, Sussex County in northwestern New Jersey are world famous for fluorescent minerals. No other site has produced more rare and interesting minerals. Over 80 fluorescent mineral samples have been taken from these mines. While other great localities can have similar minerals, no location on earth compares with the minerals of Franklin and Sterling Hill, New Jersey.

The city of Franklin calls itself "The Fluorescent Mineral Capital of the World"! We can't imagine a fluorescent mineral display that does not contain a specimen from Franklin or Sterling Hill. The most common specimens from these localities can literally "light up" a fluorescent display with beautiful reds (Calcite) and greens (Willemite) under short-wave ultraviolet light. These specimens are made even more interesting with a mix of non fluorescent black (Franklinite) contrasting the fluorescent display with black designs. Other fluorescent minerals from here include Esperite (bright yellow-green), Clinohedrite (orange-yellow), Hardystonite (violet-blue), Barite (white), Manganaxinite (an intense red) and Wollastonite (bright-yellow) to name a few.

Sadly, the mines are now closed and filled with water and rock. Only a few mine dumps remain to provide any new material. Two museums are present to educate the public about these remarkable mines and one allows tours into some of the actual mine shafts and both provide mine dump collecting opportunities. It is easy to see that these mines are truly one of the best mineral localities to ever be discovered and specimens from them should be treasured.

Most of the specimens available now are from the "trailings" or dump sites known as "dumps". This is the material that
was removed from the mines many years ago. Specimens from the famous Trotter Dump and the Buckwheat Dump
are highly collectible but the true prize comes from old stock specimens actually removed from the mines and stored
without being weathered and oxidized. Franklinite is a prized mineral if found in its crystal form. Older specimens from
these areas had large Franklinite inclusions and large patches of Calcite and Willemite and are referred to as "Jumbo"
series specimens.

A very rich example of massive franklinite. This is a small cabinet specimen of black, metallic to sub-metallic franklinite. This piece has a parting texture that is easily mistaken for a cleavage which franklinite lacks. This specimen is a very good example of what looks like granular texture that is actually anhedral crystals of franklinite. Sections and grains of a vitreous orange-brown garnet are mixed in the Franklinite. This is an excellent example of the textural properties of franklinite..

Specimen weighs 19.9 oz or 1.24 lbs (565g) and measures 3.5 x 3.4 x 1.6 inches (9 x 8.8 x 4.2cm)

Tephroite with exsolution Willemite lamallae with Calcite and minor Hendricksite

$49.00

Sterling Hill Mine

This specimen is Brown Tephroite with exsolution (which is the process by which a solid or molten rock, separates into its component minerals upon cooling) Willemite lamellae (which is a thin plate or layer), with calcite and minor Hendricksite from Sterling Hill Mine, NJ. It is fluorescent under shortwave UV light. The Willemite fluoresces green, calcite orange-red, the Tephroite and Hendricksite are non-fluorescent.

Willemite can form during exsolution, intimately mixed with other minerals; at Franklin these include pale green Petedunnite, blue Vesuvianite (var. cyprine), gray Tephroite, or pink Bustamite. At Sterling Hill the Tephroite is usually brown, and can include striking patterns of Willemite exsolution lamellae.

These hard to find rare specimens are highly prized by collectors. Photos taken in a blackout box with a Nikon CoolPix L-1 under a "Way Too Cool" 254 nm SW 9-Watt Ultra Violet Lamp. Own a RARE Sterling Hill Classic!

Extra Large Mylonite Ore from Sterling Hill NJ

$249.00

Sterling Hill Mine

Mylonite Ore is an ore that has been mylonitized or "stretched" by metamorphic processes. It is a fine-grained, compact metamorphic rock produced by dynamic recrystallization of the component minerals resulting in a reduction of the grain size of the rock. Mylonites can have many different mineral compositions. Classification of Mylonite Ore is based on the textural appearance of the rock.

Mylonites are rocks that have been deformed by a large shear strain in ductile fault zones. This Mylonitized ore (Willemite, Franklinite and Calcite) is from the 750 foot level, close to the zero fault area, in Sterling Hill, Ogdensburg, NJ. The Willemite is a fluorescent green, Calcite red-orange, and the Franklinite is non-fluorescent under shortwave UV light.

These hard to find rare specimens are highly prized by collectors. Photos taken in a blackout box with a Nikon CoolPix L-1 under a "Way Too Cool" 254 nm SW 9-Watt Ultra Violet Lamp. Own an Extra Large RARE Sterling Hill Classic!
