Abalone is a beautiful shell from the Family Haliotidae and Genus Haliotis. Haliotis (“sea ear”) is called Abalone when it is found off the North American coast. There are 8 species of haliotis (plus hybrids) found off the west coast of North America, primarily from middle California, US to Baja California, Mexico. There is also one species found on the east coast.
Haliotis is called Paua when found off the coast of New Zealand, Awabi off the coast of Japan, Mutton Fish off the coast of Australia, and Omer off the coast of Guernsey.
Abalone, paua, etc have a row of holes down the side of the shell. These are respiratory pores. These holes are sometimes present in the pieces I use and are a totally natural part of the shell. Unless otherwise stated in the description, the abalone shell I use is totally natural (no dyes) and either polished or tumbled to bring out the shine.
Aventurine is a form of quartz, characterised by its translucency and the presence of platy mineral inclusions that give a shimmering or glistening effect termed aventurescence.
The most common colour of aventurine is green, but it may also be orange, brown, yellow, blue, or gray. Chrome-bearing fuchsite (a variety of muscovite mica) is the classic inclusion, and gives a silvery green or blue sheen. Oranges and browns are attributed to hematite or goethite. Because aventurine is a rock, its physical properties vary: its specific gravity may lie between 2.64-2.69 and its hardness is somewhat lower than single-crystal quartz at around 6.5.
Aventurine feldspar or sunstone can be confused with orange and red aventurine quartzite, although the former is generally of a higher transparency. Aventurine is often banded and an overabundance of fuchsite may render it opaque, in which case it may be mistaken for malachite at first glance.
The name aventurine derives from the Italian “a ventura” meaning “to cometh”. This is an allusion to the lucky discovery of aventurine glass or goldstone at some point in the 18th century.
Although it was known first, goldstone is now a common imitation of aventurine and sunstone. Goldstone is distinguished visually from the latter two minerals by its coarse flecks of copper, dispersed within the glass in an unnaturally uniform manner. It is usually a golden brown, but may also be found in blue or green.
The majority of green and blue-green aventurine originates in India (particularly in the vicinity of Mysore and Madras) where it is employed by prolific artisans. Creamy white, gray and orange material is found in Chile, Spain and Russia. Most material is carved into beads and figurines with only the finer examples fashioned into cabochons, later being set into jewellery.
Main markets for aventurine are landscape stone, building stone, aquaria, monuments, and jewellery

Amazonite (sometimes called “Amazon stone”) is a green variety of microcline feldspar.
The name is taken from that of the Amazon River, from which certain green stones were formerly obtained, but it is doubtful whether green feldspar occurs in the Amazon area.
Amazonite is a mineral of limited occurrence. Formerly it was obtained almost exclusively from the area of Miass in the Ilmen mountains, 50 miles southwest of Chelyabinsk, Russia, where it occurs in granitic rocks. More recently, high-quality crystals have been obtained from Pike's Peak, Colorado, where it is found associated with smoky quartz, orthoclase, and albite in a coarse granite or pegmatite. Crystal Peak, Teller County, Colorado is a well-known locality for crystals of amazonite. Some other localities in the United States yield amazonite, and it is also found in pegmatite in Madagascar.
Because of its bright green colour when polished, amazonite is sometimes cut and used as a gemstone, although it is easily fractured.
For many years, the source of amazonite's color was a mystery. Naturally, many people assumed the color was due to copper because copper compounds often have blue and green colors. More recent studies suggest that the blue-green color results from small quantities of lead and water in the feldspar. (Hoffmeister and Rossman, 1985.
Amazonite is a gem variety of microcline feldspar and is usually polished as a cabochon. 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. The schiller is caused by a feature of the stone's crystal structure. Orthoclase feldspar and albite are present in close association, arranged in layers. This causes an interference effect of light.
Amazonite is found in the United States, Brazil, Zimbabwe, Russia, Australia, Namibia. Amazonite is usually light green to blue-green, mottled and sometimes contains light striations.
Ammonites are an extinct group of marine animals of the subclass Ammonoidea in the class Cephalopoda, phylum Mollusca. They are excellent index fossils, and it is often possible to link the rock layer in which they are found to specific geological time periods.
Ammonites’ closest living relative is probably not the modern Nautilus (which they outwardly resemble), but rather the subclass Coleoidea (octopus, squid, and cuttlefish).
Their fossil shells usually take the form of planispirals, although there were some helically-spiraled and non-spiraled forms (known as “heteromorphs”). Their name came from their spiral shape as their fossilized shells somewhat resemble tightly-coiled rams’ horns. Pliny the Elder (d. 79 A.D. near Pompeii) called fossils of these animals ammonis cornua (“horns of Ammon”) because the Egyptian god Ammon (Amun) was typically depicted wearing ram’s horns. Often the name of an ammonite genus ends in -ceras, which is Greek (κρας) for “horn” (for instance, Pleuroceras).
Other fossils, such as many found in Madagascar and Alberta (Canada), display iridescence. These iridescent ammonites are often of gem quality (ammolite) when polished. In no case would this iridescence have been visible during the animal’s life; additional shell layers covered it.

Azurite is an intense deep blue color. Different sources claim the name is derived from the Persian word lazhward or from the Arabic word azul, both of which mean blue.
It often occurs with malachite, chrysocolla or turquoise in areas with copper deposits. A rare form called “Bluebird”, has dark red Cuprite mixed with azurite. Azurite is found in Australia, Chile, France, Mexico, Morocco, Nambia, the southwestern USA, and Zaire.
For thousands of years this stone has been used in jewelry and ornamental objects. During the Middle Ages and Renaissance it was ground into pigment for use in paint and eye shadow
Azurite crystals are monoclinic, and when large enough to be seen they appear as dark blue prismatic crystals. Azurite specimens are typically massive to nodular, and are often stalactitic in form. Specimens tend to lighten in color over time due to weathering of the specimen surface into malachite. Azurite is destroyed by heat, losing carbon dioxide and water to form black, powdery copper oxide. Characteristic of a carbonate, specimens effervesce upon treatment with hydrochloric acid.
Azurite was used as a blue pigment for centuries. Depending on the degree of fineness to which it was ground, and its basic content of copper carbonate, it gave a wide range of blues. It has been known as mountain blue or Armenian stone, in addition it was formerly known as Azurro Della Magna (from Italian). When mixed with oil it turns slightly green. It is also known by the names Blue Bice and Blue Verditer. Older examples of azurite pigment may show a more greenish tint due to weathering into malachite. Much azurite was mislabeled lapis lazuli, a term applied to many blue pigments. As chemical analysis of paintings from the Middle Ages improves, azurite is being recognized as a major source of the blues used by medieval painters. True lapis lazuli was chiefly supplied from Afghanistan during the Middle Ages while azurite was a common mineral in Europe at the time. Sizable deposits were found near Lyons, France. It was mined since the 12th century in Saxony, in the silver mines located there.
