Amazonite, also known as “hope stone”, is a semi-opaque gem variety of microcline feldspar. Usually cabochon-cut and polished, it displays a schiller of light which is caused by inclusions. Schiller is a lustrous reflection from planes in a mineral grain and is similar to what is more commonly known as iridescence. Amazonite varies from bright verdigris green to a bluish green
Amethyst is a violet variety of quartz often used in jewelry. The name comes from the Ancient Greek for "not” "intoxicated", a reference to the belief that the stone protected its owner from drunkenness. Amethyst occurs in primary hues from a light pinkish violet to a deep purple. Amethyst may exhibit one or both secondary hues, red and blue. Amethyst is found around the world most notably in large quantities in Brazil.
Angelite or Blue Anhydrite is a fairly new discovery in the gem and mineral world. Discovered in 1987 in Peru, during the Harmonic Conversion, its colors may be white, gray or colorless, as well as blue to violet. Anhydrite comes from Mexico; Peru; Germany and New Mexico.
Aquamarine (from Latin: aqua marina, "water of the sea") is a blue or turquoise variety of beryl. It occurs at most localities which yield ordinary beryl. In the United States, aquamarines can be found at the summit of Mt. Antero in the Sawatch Range in central Colorado. In Wyoming, aquamarine has been discovered in the Big Horn Mountains, near Powder River Pass. In Brazil, there are mines in the states of Minas Gerais, Espírito Santo, and Bahia, and minorly in Rio Grande do Norte. The Mines of Colombia, Zambia, Madagascar, Malawi, Tanzania and Kenya also produce aquamarine.
Onyx is a banded variety of chalcedony. Onyx comes through Latin (of the same spelling), from the Greek meaning "claw" or "fingernail". Black Onyx is found around the world and is the most sought after type of Onyx.
Blue topaz is the state gemstone of Texas. Naturally occurring blue topaz is quite rare. Topaz is a silicate mineral of aluminium and fluorine.
Carnelian is a variety of chalcedony or cryptocrystalline quartz that comes in hues from deep red to orange. Most carnelian comes from India but also from South America. It is the zodiac birthstone for Virgo. Historically, carnelian was a favored gem of nobility. Often, Indian aristocracy was buried with this stone by their side. Some believe carnelian boosts energy levels and wards off poverty, thus the proverb, "No man who wore a carnelian was ever found in a collapsed house or beneath a fallen wall." Many carnelians being offered in the market today are actually agates which have been dyed and then heat-treated. But there is a way to identify natural carnelian. The dyed agate will display striping when held against the light, while the natural carnelian will show a cloudy distribution of color. Natural carnelian is increasingly rare.
Notable occurrences include Israel, Democratic Republic of Congo, Chile, Cornwall in England, and Arizona, Utah, Idaho, New Mexico and Pennsylvania in the United States.
Green Amethyst is actually Prasiolite which comes from the Greek or “leak-green”. Prasiolite is a golden green quartz, somewhat similar in color to peridot or gold-green beryl. Only quartz from the Montezuma deposit in Minas Gerais, Brazil can be heated to produce prasiolite.
Its name is derived from a visual effect, or sheen, caused by light reflecting internally in the moonstone from layer inclusion of different feldspars. Moonstone is composed of two feldspar species, orthoclase and albite. The two species are intermingled. Then, as the newly formed mineral cools, the intergrowth of orthoclase and albite separates into stacked, alternating layers. When light falls between these thin, flat layers, it scatters in many directions producing the phenomenon called adularescence. Deposits of moonstone occur in Australia, the Austrian Alps, Mexico, Madagascar, Burma, Norway, Poland, Sri Lanka and the United States.
Honey Rutilated Quartz
Honey Rutilated Quartz is a macrocrystalline variety of Quartz with needlelike rutile (titanium dioxide), embedded in it. It is found in Australia, Brazil, Kazakhstan, Madagascar, Norway, Pakistan and the United States.
Is a feldspar mineral. It occurs in large crystal masses in anorthosite and shows a play of colors called labradorescence. The labradorescence, or schiller effect, is the result of light refracting within lamellar intergrowthsThe geological type area for labradorite is Paul's Island near the town of Nain in Labrador, Canada. It has also been reported in Norway and various other locations worldwide.
Also called "Stefilia's Stone", is a rare blue variety of pectolite found only in the Dominican Republic, in the Caribbean. Its coloration varies from white, light-blue, green-blue to deep blue.
