OnyxOnyx (ONX)
Onyx, or Black Chalcedony, is readily available from Italy, Mexico, the United States, Russia, Brazil, and South Africa. Onyx is strength giving and provides support in difficult or confusing times. Onyx also promotes vigor and stamina. It also assists in keeping counsel. Physically, Onyx assists in absorbing from the universe energies that are required for healing. Onyx is beneficial for teeth, bones, bone marrow, blood disorders, and the feet.
Mother of PearlMother of Pearl is a very strong, resilient, and iredescent shell formed on the inside of some mollusks. It is also what makes up pearls. The pearl oyster, freshwater pearl mussels, and abalone are the highest yielding sources of Mother of Pearl. Mother of Pearl is believed to attact prosperity. It protects from and transmutes negative energy. It is particularly powerful in the protection of children. A traditional metaphysical use fo mother of pearl is cleansing an enviornment, and recalling primordial memories. Physically, Mother of Pearl is good for high blood pressure, dizziness, cataracts, and wound healing.
Nacre pronounced /ˈneɪkər/ or "NAY-kər", also known as Mother of Pxearl, is an organic-inorganic composite material produced by some mollusks as an inner shell layer; it is also what makes up pearls. It is very strong, resilient, and iridescent.
Nacre is found in some ancient lineages of bivalve gastropod and cephalopod. The inner layer in the great majority of mollusk shells is porcellaneous, not nacreous, frequently resulting in a non-iridescent shine or less commonly in non-nacreous iridescence such as flame structure (e.g. conch pearl).
Pearls and the inside layer of pearl oyster and freshwater pearl mussel shells are made of nacre. Many other families of mollusk also have a nacreous inner shell layer, including marine gastropods such as the Haliotidae, the Trochidae and the Turbinidae.
Nacre appears iridescent because the thickness of the aragonite platelets is close to the wavelength of visible light. This results in constructive and destructive interference of different wavelengths of light, resulting in different colors of light being reflected at different viewing angles.
Nacre formation is mediated by the organic matrix, which controls the onset, duration and form of crystal growth. Individual aragonite "bricks" quickly grow to the full height of the nacreous layer, and expand until they abut adjacent bricks. Bricks nucleate on randomly-dispersed elements within the organic layer. This produces the hexagonal close-packing characteristic of nacre. Nacre differs from fibrous aragonite – a brittle mineral of the same form – in that the growth in the c-axis (i.e. perpendicular to the shell, in nacre) is slow in nacre, and fast in fibrous aragonite
