Here is a very different, very beautiful specimen of Terlingua Calcite
from Mexico. It has a pretty soft pink color around the edges to a
purple in the center in normal light and shows a bright pink under long
wave UV light. This nice specimen measures 3 1/8" x 3" x
1 1/8".

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.

Here's a cool new item, a very nice Sweetwater Agate from Wyoming. It has
an interesting shape and great change of color under SW UV lights.
It measures 3" x 1 3/4" x 1 3/8". It has been tumbled right here in
our very own Lapidary Department and has a smooth texture and slight
polish. Something very different!

Agates mostly occur as nodules in volcanic rocks or waters
containing Silica in solution which is possibly derived from the
decomposition of Silicates in the lava. The Siliceous matter is deposited
in regular layers resulting in the banded or striped formation. It is very
unlikely that you would ever find an exact duplicate of any type of Agate,
Brazilian or other.

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. |

This is a different item, a nice specimen of Adamite from Mexico. This
mineral has nice light yellowish green tinted druzy crystals in unidentified matrix.
The sparkly crystals show a pretty green under long wave UV light. The unique specimen measures
5 1/8" x almost 4 3/4" x nearly 2 3/4". Make it part of your mineral
collection!

Adamite is a zinc arsenate hydroxide mineral that is normally
colorless. Yellow tint in the crystals indicates FE compounds and a green
tint shows copper substitutions in the structure. The yellow to bright
lime green crystals and their fluorescence are a favorite among mineral
collectors.

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.

M806b Here is a nice Tungsten and Scheelite
ore specimen from Trumbull, Connecticut. The Tungsten isn't
distinguishable from the the tan and grayish brown matrix until under UV
light. The specimen measures 1 7/8" x nearly 1 5/8" x 1 1/4" and has a
natural unpolished appearance. The Tungsten shows a pretty Blue glow under
short wave UV light.

Tungsten
is a brittle, hard, corrosion resistant metallic element wolframite,
scheelite or similar minerals. It has highest melting point and lowest
vapor pressure of any metal. It white to grayish in color and used in
electrical contacts, rocket nozzles, solar- energy devices and any
place where hardness and strength are important.

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.

Barite or Baryte is a mineral consisting of Barium sulfate and is
generally white or colorless. The baryte group consists of baryte,
celestine, anglesite and anhydrite. Baryte commonly occurs in lead-zinc
veins in limestones, in hot spring deposits, and with hematite ore. It
is used in the manufacture of paints and paper. Although Barite contains
a 'heavy' metal, Barium, it is not considered to be a toxic chemical
because of its extreme insolubility.

Here is something different for the mineral collector, a nice
Selenite Rose specimen. This material has a unique appearance much like a
frosted pine cone cluster in normal light and has a pale blue
color under SW UV light and a pretty silvery white under a LW UV light. This specimen measures approximately
1 7/8" x
1 5/8" x 1 3/8". Very cool!

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.

Chalcedony is a cryptocrystalline form of silica, composed of very fine
intergrowths of the minerals quartz and moganite.
Chalcedony 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. |

Coral is built by secreting calcium carbonate skeletons. Hard
coral is fossilized over millions of years. It can be almost any color.
The stony Corals are often found in Coral reefs, large structures
generally found in tropical waters. Reefs are extremely diverse consisting
of over 4,000 species of fish, cnidarians, mollusks, crustaceans, and
other animals.
