The mysterious appeal of
gem stones, their exquisite colors, and the play of light
would alone have made them precious to many, but their
rareness, hardness, and durability have made them double
valuable.
A semi precious stone
should be a mineral, that is, an object formed spontaneously
in nature without human intervention, this property is
essential in our definition.
Gemstones are minerals that
are treasured for their beauty and durability. A large number
of minerals have been used as gems. Their value generally
depends on four elements: the beauty of the stone itself; its
rarity; its hardness and durability; also the skill with which
it has been cut and polished, and presented gives also a
higher value to any stone.
Semi precious stones are
the minerals, with less hardness and less rarity, compared to
precious stones like emerald and sapphire, as for the beauty
and durability of these stones, they are not to be questioned.
A famous property presented
in semi precious stones is dichroism, the ability of some
gemstone to present two different colors when viewed in
different directions; and transparency.
In certain gemstone,
notably opals, brilliant areas of color can be seen within the
stone; these areas change in hue and size as the stone is
moved. This phenomenon, known as play of color, similar
appearance could be seen on some rare shells also. Gems that
are fibrous in structure show irregular interior reflections
similar to those seen on watered or moiré silk. This optical
property, which is called chatoyancy, is exhibited by several
gems, notably the tiger's eye and cat's-eye.
As for the new
revolutionary idea of using semi precious stones, it is after
hard efforts and researches that ULTIMATE STONE achieved this
project, the main difficulty was created by distance only:
especially to find each semi precious stone suitable for this
kind of use, that already are brought from the four corners of
the world, like Brazil, India, Madagascar, Congo, Russia,
Afghanistan, Indonesia etc…
As for now, ULTIMATE STONE
is still searching for the more prestigious ways to use these
semi precious stones. |
