M800b Here's a
new item, a very cool Yooperlite. It's a pretty plain looking rock in
color until under a LW UV light shows a pretty bright yellow color almost
looking like a volcano bursting lava from within. It
also has lots of sparkle. This nice specimen measures 2 1/4" x 1 3/8" x
1 1/8".

Yooperlites were recently discovered on the shores of Lake Superior
in Michigan's Upper Peninsula by Eric Rintamaki. They are syenite rocks
that contain sodalite, a fluorescent mineral that has never before been
identified in Michigan. The sodalite is what gives the Yooperlites their
glow under a UV lamp. Yooperlite is derived from the nick name
Yoopers which is what the folks in that area call themselves.

Here is a
neat set of of 2 smaller Dugway Geodes from an unknown location in
Utah. They have
a very cool cavity and measures 2 1/4" x 2 3/8" x 1 1/8",
2 3/8" x 2 3/8" x 1".
It has a lovely pale grey colored Quartz inside the sparkly crystal cavity
that fluoresces a cool green color under a short wave UV light. Under
a UV/LW (not shown) is has more of a blue-green color. The face of
of the cavities have been polished. This specimen is a beautiful work
of nature.

Geodes are geological rock formations which occur in sedimentary and
certain volcanic rocks. They are essentially rock cavities or vugs with
internal Crystal formations or concentric banding. The exterior is generally
Limestone while the interior contains Quartz Crystals and/or Chalcedony deposits.
If the Geode is completely filled with Crystal, being solid all the way through,
it is then called a nodule.

M802c This
is an interesting and fairly rare Kunzite crystal specimen. It is
a pale purple in normal light and fluoresces a cool reddish orange
under long wave UV light. The specimen is 2 7/16" long x 1 1/4" x
almost 1/2" thick. An excellent addition to any serious fluorescent mineral collection.

Kunzite, or a form of Spodumene is a pyroxene mineral consisting of lithium
aluminium inosilicate, and is a source of lithium. It occurs as colorless
to yellowish, purplish, or lilac kunzite, prismatic crystals, often of great size. Kunzite
was discovered at the Pala Chief Mine near San Diego, California and named
after gemologist GF Kunz, who first described it after the turn of the
twentieth century. Kunzite is an unusual and rare stone. |

Chalcedony is a cryptocrystalline form of
silica, composed of very fine intergrowths of the minerals quartz and
moganite.
It has
a waxy luster, and may be semitransparent or translucent. It can assume a
wide range of colors, but those most commonly seen are white to gray,
grayish-blue or a shade of brown ranging from pale to nearly black.

Manganocalcite or Manganoan Calcite is a Manganese rich mineral that
gives it it's pink color. It is sometimes confused with Rhodocrosite.
Manganocalcite is sometimes called the "Reiki Stone" as it is said
to have healing properties.

Fluorite, also referred to as fluor-spar, is a mineral composed of Calcium
Fluoride. It is a widely occurring mineral found world wide and is often
found with metallic minerals such as Galena, Sphalerite, Barite, Quartz
and Calcite. Fluorite may fluoresce strongly in ultraviolet light
which may be due to the presence of some impurities such as Yttrium.
Blue is the most common color but red, purple, green, yellow and white are
also frequent. It can be used in high performance telescopes, camera
lens, enamels and in the making of opalescent glass.

Quartz is the second most common mineral in the Earth's continental
crust. It is mainly composed of Silica or Silica based minerals.
Although Quartz is known by a variety of names, the most important distinction
between types of Quartz is that of macro-crystalline, individual crystals
visible to the unaided eye, and micro-crystalline, where aggregates of crystals
are only visible under high magnification. There are many forms of Quartz
including Chalcedony, Amethyst, Citrine, and Carnelian which are results of
mineral impurities or heat treatments.
Enhydro Bubble is water that was trapped inside a crystal or agate
during it's formation.Enhydro Crystal is a Quartz or Agate stone that
contains bubbles of water inside.The most valuable Enhydro Crystals are
those that have moving bubbles.An air pocket is present in the crystal,
causing the water bubble to move up and down right within the pocket.
Other Enhydro Crystals also have water bubbles inside them, but they are
usually stationary.

Amber is the common name for the fossil resin or tree sap that is
appreciated for its inherent and interesting mixture of color. It is
widely used for the manufacture of ornamental objects including jewelry.
Although it is not mineralized, it is sometimes considered and used as a
gemstone. Most of the world's Amber is in the range of 30-90 million
years old.

A Ruby is a variety of the
mineral
corundum (aluminum
oxide). The color comes mainly from the
chromium element. The Ruby is considered one of the four
precious stones,
together with the
sapphire, the
emerald, and the
diamond. Rubies were found for centuries
in Burma. They have also been found in Thailand, Sri Lanka,
Madagascar, Vietnam, Nepal and Pakistan. Rubies have been found in the US
states of Montana, North and South Carolina.

quartz usually fluoresces green. The Jasper center color varies from tan
to peach, brown, reddish and salmon. Youngite is used in making gemstone
beads or cabochons and is very hard.

Selenite, also known as Satin Spar, Desert Rose and Gypsum
Flower, is a variety of Crystalline Gypsum. Gypsum is a very soft mineral
composed of Calcium Sulfate. Gypsum Flowers are rosette shaped Gypsum
with spreading fibers and can include an outer druze of sand or with sand
throughout. The difference between Desert Roses and Gypsum Flowers is
that Desert Roses look like roses, whereas, gypsum flowers are a myriad of
shapes.

Franklinite, named for Benjamin Franklin, is found in Franklin
and Sterling Hill, Sussex County, New Jersey. It is black in color and a
slightly magnetic member of the spinel group.
Willemite is a rare nesosilicate and zinc mineral found
principally in Franklin, New Jersey with Franklinite and Zincite.
Willemite can have a variety of colors from white, colorless, reddish,
green, yellow, orange and black. It is known for its brilliant green
fluorescence.
Calcite is a Carbonate mineral that is most widely distributed on
the Earth's surface. It is a common constituent of sedimentary rocks
with Limestone in particular. A Calcite formation can take on many
different shapes and sizes which is dependent on the location, ground
water occurrence and temperature. Calcite is usually white or
colorless but can be gray, red, yellow, green, blue, violet, brown or
black. The deeper the color is usually indicative of the definitive
impurities from the earth or water.
