Peridot Beads
Peridot is the best known gem variety of olivine, a species name
for a series of magnesium-iron rich silicate minerals. This bright
yellow-green to green gemstone has caught the fancy of humans for
thousands of years. Some historians even suspect that at least some
of the "emeralds" worn by Cleopatra were actually peridot. Much of
its recent popularity can be explained by its currently being
recognized as the birthstone for the month of August, people wear
the stone because it is supposed to bring the wearer success, peace,
and good luck..

ALLOY
An alloy is a solid solution or homogeneous
mixture of two or more elements, at least one of which is a metal, which
itself has metallic properties. It usually has different properties from
those of its component elements.
Alloying one metal with others often enhances its properties. For
instance, steel is stronger than iron, its primary element. The physical
properties, such as density, reactivity, Young's modulus, and electrical
and thermal conductivity, of an alloy may not differ greatly from those
of its elements, but engineering properties, such as tensile strength
and shear strength may be substantially different from those of the
constituent materials. This is sometimes due to the sizes of the atoms
in the alloy, since larger atoms exert a compressive force on
neighboring atoms, and smaller atoms exert a tensile force on their
neighbors, helping the alloy resist deformation. Alloys may exhibit
marked differences in behavior even when small amounts of one element
occur. For example, impurities in semi-conducting ferromagnetic alloys
lead to different properties, as first predicted by White, Hogan, Suhl,
Tian Abrie and Nakamura. Some alloys are made by melting and mixing two
or more metals. Brass is an alloy made from copper and zinc. Bronze,
used for statues, ornaments and church bells, is an alloy of tin and
copper.
Unlike pure metals, most alloys do not have a single melting point.
Instead, they have a melting range in which the material is a mixture of
solid and liquid phases. The temperature at which melting begins is
called the solidus and the temperature when melting is complete is
called the liquidus. However, for most alloys there is a particular
proportion of constituents which give them a single melting point or
(rarely) two. This is called the alloy's eutectic mixture.
