AGATES are
semiprecious silica mineral, a variety of chalcedony that occurs in
bands of varying color and transparency. Varieties are characterized
by peculiarities in the shape and color of the bands, which are seen
in sections cut at right angles to the layers. Agate is found
throughout the world, commonly in cavities in eruptive rocks and in
geodes. The middle picture above is an agate found in Mexico called
Mexican Crazy Lace agate. The bottom picture above is a Montana Moss
agate. |

AMBER is
fossil tree resin that has achieved a stable state through loss of
volatile constituents and chemical change after burial in the
ground. Amber has been found throughout the world, but the largest
and most significant deposits occur along the shores of the Baltic
Sea in sands 40,000,000 to 60,000,000 years old.
Amber occurs as
irregular nodules, rods, or drop-like shapes in all shades of yellow
with nuances of orange, brown, and, rarely, red. Milky-white opaque
varieties are called bone amber. The turbidity of some amber is
caused by inclusions of many minute air bubbles. Many hundreds of
species of fossil insects and plants are found as inclusions. Deeply
colored translucent to transparent amber is prized as gem material.

 |
AMETHYST
is a transparent,
coarse-grained variety of the silica mineral quartz that is valued
as a semiprecious gem for its violet color. It contains more iron
oxide than any other variety of quartz, and experts believe that its
color arises from its iron content. Other theories attribute the
color to contained manganese or hydrocarbons.
The
name, derived from the Greek amethystos, “not intoxicated,”
expresses the ancient folk belief that the stone protects its owner
against drunkenness. In ancient writings the Latin name amethystus
was used for amethyst, purple corundum, and purple garnet. |
 |
AMMONITES
are fossilized cephalopods, forms
related to the modern pearly nautilus. Ammonites became extinct at
the same time as dinosaurs, about 65 million years ago. |
 |
APATITE
is
any member of a series of phosphate minerals, the world's major
source of phosphorus, found as variously colored, glassy crystals,
masses, or nodules. |
 |
AQUAMARINE is
a member of the Beryl family and gets its name from two Latin words
that mean "water" and "sea". This lovely pale
greenish-blue or various tints of blue gem has been popular since
400 BC. Almost all gem quality aquamarine comes from Brazil, and is
now scarce and very costly. |
 |
ARIZONA

TURBO SHELL is
a nautilus shaped shell with marbled aqua blue, brown, and white.
Common to the Indian Ocean. |
 |
CARNELIAN
is a translucent,
semiprecious variety of the silica mineral chalcedony. It gets its
name from the Latin cornum (cornel berry or cronelian cherry). Its
red color is due to the presence of iron. It is a close relative of
sard, differing only in the shade of red. Carnelian was highly
valued and used in rings and signets by the Greeks and Romans, some
of whose intaglios have retained their high polish better than many
harder stones. |
 |
CHALCEDONY
is a very fine-grained variety of the silica mineral quartz usually
bluish white, gray, yellow, or brown. In all ages chalcedony has
been the stone most used by the gem engraver, and many colored
varieties are still cut and polished as ornamental stones. |
 |
CHAROITE
is a rare and expensive mineral only found in Russia. It has a
soft shade of purple to deep purple. Ribbons of a translucent cream
color mineral runs through most pieces of Charoite. |
 |
CHINESE
WRITING STONE
is limestone with andalusite crystals found primarily in
California. It got its name from the Chinese character appearance of
the crystal formations. The base color of the stone can be black,
grayish black, or a green-tinted black. The andalusite, or aluminum
silicate mineral, crystals are a milky white.
|
 |
CHRYSOCOLLA
is a silicate mineral, hydrated copper silicate, formed as a
decomposition product of copper minerals in most copper mines,
especially in arid regions. It occurs as crusts or masses in the
upper parts of copper-ore veins where the copper minerals have been
altered by water containing dissolved silica. |
 |
CHRYSOPRASE
Chrysoprase is a brittle, translucent, semiprecious chalcedony,
a variety of the silica mineral quartz. It owes its bright
apple-green color to colloidally dispersed hydrated nickel silicate.
Its physical properties are those of quartz. Typical occurrences are
in serpentine as a secondary mineral found in cavities and veins;
California and Silesia have notable deposits.
|
 |
CORAL
is the skeletal material of calcium carbonate built up by small
animals that live in colonies in the sea. This material is usually
branchlike and occurs in a variety of colors, of which the most
sought after are rose red to red. The best coral comes from the
Mediterranean Sea, particularly off the coasts of Algeria and
Tunisia. |
 |
DALMATIAN
DOLOMITE is a type of limestone, the carbonate fraction of which
is dominated by the mineral dolomite, calcium magnesium carbonate.
The stone is named for spotted pattern like the Dalmatian dog. |


| |

is Uvarovite, the pink is Cobalto Calcite, and the multi-colored is
the Rainbow Pyrite. |
 |
FOSSIL
IVORY Prehistoric woolly mammoth ivory is collected from
the rivers of Alaska and Northern Canada, where it has come to rest
by natural erosion. As the glaciers recede, the ivory is exposed and
found by local hunters. The woolly mammoth roamed North America,
Europe, and Asia during the last ice age about 10,000 to 20,000
years ago. |
 |
FOSSIL
TURTLE SHELL has rich texture and color and is very rare. |
 |
FOSSILS,
GENERAL occur
mainly in sedimentary rocks. They are the remains of animals and
plants preserved in the layers of sediment. The types of fossil that
are found in a rock give an indication of the rock’s origin: a
marine fossil, for instance, suggests that the rock formed from
sediments deposited in the sea. |
 |
FUCHITE
is
found in Russia and has glitters of blue and green mixed with cream.
|
 |
GARNET
is any member of a group of common silicate minerals that have
similar crystal structures and chemical compositions. They may be
colorless, black, and many shades of red and green.
|
 |
GASPEITE
is a very bright and intense
yellowish green color. It’s a rather soft stone, and can be
polished to a very nice shine. |

|
Inlay,
or Intarsia, is the result of a process that combines a variety
of stones attaching them to one another with mastic. The combined
stone is then cut and polished to look like one piece. Any stones
can be combined to achieve different results. Each one is a tiny
work of art! Shown here are inlay works with Malachite & Lapis
(top) and Sugilite & Opal (bottom).
|
 |
IOLITE,
also called cordierite, is a silicate of
aluminum and magnesium. Its name is derived from the Greek ios
(violet) and lithos (stone). Iolite is sometimes called water
sapphire because of its color. The color is mostly purplish-blue and
very strong in one direction, changing to pale grayish-blue to
nearly colorless or yellowish as the stone is turned. Transparent to
translucent, inclusions are very common. Most Iolite is found in
water-worn pebbles from gem gravel beds. Often found in Connecticut,
Wyoming and Finland.
|
 |
LABRADORITE
is
a feldspar mineral in the plagioclase series that is often valued as
a gemstone and as ornamental material for its red, blue, or green
iridescence. The mineral is usually gray or brown to black and need
not be iridescent; when used as a gem it is usually cut as a
cabochon (with a rounded convex surface). Labradorite is named for
its occurrence near Nain, on the coast of Labrador, Canada
|
 |
LAPIS,
full name Lapis Lazuli, is a semiprecious stone valued for its
deep blue color. The source of the pigment ultramarine, it is not a
mineral but a rock colored by lazurite. In addition to the sodalite
minerals in lapis lazuli, small amounts of white calcite and of
pyrite crystals are usually present. Diopside, amphibole, feldspar,
mica, apatite, titanite (sphene), and zircon may also occur.
|
 |
LAVA
is the hardened and cooled magma (molten rock) poured out onto
the Earth's surface at temperatures from about 1,300° to 2,200° F.
Thin lava flows generally contain many holes, or vesicles, left by
bubbles of gas frozen into the congealing liquid. Thick flows, which
remain hot for long periods, may lose most of their gas before the
lava congeals, and the resulting rock may be dense with few
vesicles. |
 |
MADAGASCAR
JASPER. Jasper is
an opaque, fine-grained or dense variety of the silica mineral chert
that exhibits various colors. This variety, found in Madagascar, is
normally tones of green and yellow |
 |
MALACHITE
is
a mineral of copper. Because of its distinctive bright green color
and its presence in the weathered zone of nearly all copper
deposits, malachite serves as a prospecting guide for that metal.
Malachite has been used as an ornamental stone and as a gemstone.

specimens are bottle green corroded masses and are found in
Czechoslovakia. |
 |
MOTHER
OF PEARL, or nacre is the iridescent substance that forms
the lining of the shells of some fresh-water and some salt-water
mollusks. Like the pearl, it is a secretion of the mantle, composed
of alternate layers of calcium carbonate and conchiolin. Among the
chief sources are the pearl oyster, found in warm and tropical seas,
chiefly in Asia; freshwater pearl mussels, which live in many rivers
of the United States, Europe, and Asia; and the abalone of
California, Japan, and other Pacific regions. |
 |

a reddish brown color.
|
 |
PEARL
is the
concretion formed by a mollusk consisting of the same material
(called nacre, or mother-of-pearl)
as the mollusk's shell. It is a highly valued gemstone.

characterized by their translucence and luster and by a delicate
play of surface color called orient. The more perfect its shape
(spherical or drop-like) and the deeper its luster, the greater its
value.
|
 |
PERIDOT,
usually yellow-green to brownish-green; prized colors are
distinctive deep yellow-greens of great uniformity. Transparent but

called rutilated quartz.
|
 |
SAPPHIRE
is transparent to
translucent, corundum, or aluminum oxide, that has been highly
prized as a gemstone since about 800 BC. Its color is due mainly to
the presence of small amounts of iron and titanium and normally
ranges from a very pale blue to deep indigo, with the most valued a
medium-deep cornflower blue. Colorless, gray, yellow, pale pink,
orange, green, violet, and brown varieties of gem corundum also are
known as sapphire; red varieties are called ruby. |
 |

is any of a group of hydrous magnesium-rich silicate minerals.
Named in allusion to its resemblance to a snake's skin, serpentine
is usually grayish, white, or green but may be yellow (chrysotile)
or green-blue (antigorite); the green color is due to iron replacing
magnesium.

a common, coarse-grained variety of the silica mineral quartz that
ranges in color from nearly black through smoky brown.
|
 |
SPECTROLITE A
native of Finland, Spectrolite is a semiprecious stone belonging to

is hydrated copper and
aluminum phosphate. It is a secondary mineral deposited from
circulating waters, and it occurs chiefly in arid environments as
blue to greenish, waxy veinlets in alumina-rich, weathered,
volcanic, or sedimentary rocks. The color of turquoise ranges from
blue through various shades of green to greenish and yellowish gray.
Turquoise is opaque except in the thinnest splinters, takes a fair
to good polish, and has a faintly waxy luster. |
