colors are usually tans and browns marked by swirling, lacy patterns.  Open holes and
irregular edges often add character to these stones.
Origin:   It is found in the Pacific Northwest in California, Nevada and Washington.
Hardness:   Probably a 6 - 7.
Description:  A striking pink (Peptobismal pink) color marked by a beautiful
crystalline surface.  So rare and recently discovered, I can't find it in my geological
reference books.  My stonecutters tell me that it is difficult to obtain, and that the best
bright colored rock is completely mined out.  Colors vary from the best bright pink to
plum and pale pink.  I have a rough time getting a hold of this stone!
Origin:   One single deposit has been discovered so far.  It is found sprinkled in an
African malachite mine in Zaire/Congo.  Very little remains in the mine.
Hardness:   A softer stone, probably a 3 or 4 on Moh's hardness scale where 10 is a
diamond.  Not good for rings or bracelets.
Description:   Often confused with turquoise.  An aqua color that often has green
(malachite) and blue (azurite) naturally combined.
Origin:  Found in the copper mine in Morena, Arizona.  The mine has recently closed
and cutters are now getting the rock from the old mine tailings.
Geology:   Copper bearing mineral found wherever copper deposits occur, especially in
areas of Arizona and Chili, and reportedly in Zaire, Australia, France, and England.
Hardness:  Soft for jewelry unless used in earrings and pendants.  If formed in quartz, it
becomes harder.  Hardness 2-4 on a 10 point scale where a 10 is a diamond.

Description:  A colorful, rare mineralized fossil with an opal-like color change of red,
green, and sometimes blue or purple.  Fiery, iridescent.  Each piece is one of a kind.
Origin:  Discovered in southern Alberta, Canada.  More than 70 million years old.
Geology:  Created from a life form called "ammonite" that roamed the subtropical seas that
bordered the Rocky Mountains.  Fossilization of the ammonite in iridescent hues, created
this new gem.  In 1981, the International Colored Gemstone Commission recognized the
organic gemstones as ammolite.  Only limited quantities are available, thereby enhancing the
See more pictures and information about these new stones in the ALL STONES section below.

Description:  This very rare copper sulfide mineral is a dark indigo blue marked with
veins of iron pyrite (fool's gold).  It was mined for it's copper content, but has been
scarce since the 70's.
Origin:  Found in the copper mines of Butte, Montana.
Hardness:  1.5 - 2.  
Description:   I carry some traditional white opals, but mostly boulder opals or mosaics.  
The boulder opals occur in a brown ironstone matrix, in thin veins or layers of color.  The
mosaics are pieces of real opal cut into squares that are placed in a mosaic pattern and
covered with a quartz cap for protection.
Origin:  Australia
Geology:  Calcium Silicate-metamorphic.

occur in a copper mine.
Origin:  Morenci, Arizona.  A second mine source in Bisbee, Arizona has been closed.
Geology:  Copper ores.  Basic copper carbonate.
Hardness:  3-1/2 to 4.  A softer stone.  Take care with stones set in rings or bracelets.  
Store separately.  No harsh cleaners.
History:  Malachite - It's name is from the Greek "maloche" or "mallow" in allusiai to it's
color.  Azurite- It's name is from the azure-blue color.
Properties:  Allows one to reach inner depths without fear.  Produces a flow to actions an
a willingness towards flexibility.  Gives comfort by calming anxieties.  Can be used to
enhance flexibility in motion and to treat disorders associated with the skin, bones, teeth and
circulatory system.  Assists in the preventions of ulcers, asthma, and stress related problems.
Description:  Striking combinations of red, black, and white mark this unusual stone.
 Shades of the red depend on where the stone is found.
Origin:  Brighter red stones are found in Quebec, Canada.  More raspberry-like
colors are from Russia.
Hardness:  5 - 5.5
Description:  A newly discovered jasper marked by orbicular or round "spotted-like"
colors of yellow, green, and red in different background colors.
Origin:  Found in the ocean-side cliffs of Madagascar.  The deposits have been mostly
depleted, so the jasper is becoming scarce.
Hardness:   7
Description:  Jasper is a form of chalcedony occurring in many colors.  It is a silicated (agatized)
volcanic ash, formed by a volcanic ash flow overlaying the basalt formation.  Often organic
material or mineral oxides like iron oxide occur in the jasper.  This creates swirls, lines bands, and
sometimes dendritic (brush-like images).  It is from the Microcene Age.
Origin:   Biggs and DesChutes jaspers were found in Oregon.  Biggs is from Biggs Junction and
was discovered in the 70's during construction of Highway 84, near Auburn.  Some of it was
collected and the rest was covered up by the highway.  As a result, it is very scarce.  The
landowner was ab le to keep what he could collect, and buried it in his yard in steel drums.  Each
year he would dig it up and sell some.  The last of it has now been sold by his family.  My
stonecutter source lost much of the jasper he had stashed when the Colorado 4-mile fire in 2010
destroyed his studio.  It has become very difficult to find good scenic pieces of jasper now.  Other
mines providing jasper include Idaho and Oregon varieties called Wild Horse, Rocky Butte,
Bruneau, Marrisonite, Willow Creek, and Owyhee to name a few.
Hardness:   7
Description:  This multi-colored, naturally colored crystalline stone is found on the
inside of geodes.  It is not color enhanced.  Colors range from bright blue to yellow,
green and pink.
Origin:  Russia
Hardness:   7                             
Description:  These are natural quartz crystalline formations found on the inside of
agate geodes.  While the crystals are natural, the color is created by a coating (or plating)
process called either "vacuum ionization" or "vapor deposition".  The color is from the
titanium coating, or layer placed over the crystals.
Origin:   Most of the geodes are from Brazil.
Hardness:   7
Description:  This is a rere formation of garnet.  It forms in crystals on a slate-like
matriz of dark grey.  A smaller deposit in Quebec has been described as having a light
colored matrix.  Uvarovite is considered a drusy gemstone.
Origin:   This quality and color comes from the Ural Mountains of Russia.
Hardness:   6.5 - 7.5
