Diamond is the birthstone of April & anniversary
gemstone for the 10th and 60th years of marriage.
Diamond was discovered in 500 B.C. in India.
The name "diamond" comes from the
Greek word "adamas" which means
unconquerable-suggesting the eternity of love.
Since ancient Greece diamonds have been the
traditional symbol of love. The ancients believed
they were hardened dew drops, splinters from
the stars or crystallized lightening. A diamond
- the hardest substance known to man is a
crystallized carbon which has unique powers
of light reflection. Because it is composed
of a single element - a diamond is the purest
of all gemstones. Diamond is a colorless stone.
Some other occasional colors are, blue, yellow,
amber, red, green, pink.
II.
The value of a diamond, 4 C's: Cut
- Clarity - Color - Carat Weight
Cut
Cut is the factor
that determines the brilliance of a
diamond. A classic round brilliant cut
diamond has 58 facets - 33 on the top,
24 on the bottom and the culet ( 1 point
at the bottom - another tiny facet ).
Each of the stone's facets must be placed
by the diamond cutter in exact geometric
relation to one another. Quality diamonds
must be properly cut and not "spread",
which means that the proper proportions
are compromised to make the stone weigh
more.

Clarity
The fewer the inclusions, the clearer, more
brilliant and more expensive the diamond.
"Flawless" diamond means that no
inclusions can be seen under a 10x jeweler's
loupe. Flawless diamonds are extremely rare.

Color
The more colorless the diamond, the more valuable
it is .Though most diamonds may appear colorless
to the eye, the majority contain slight traces
of yellow or light brown. Depending on the
stone's size, a single increase in color grade
can boost a value of a diamond by thousands
per carat. A traditional engagement diamond
is colorless or near colorless.
In nature diamonds can also occur in shades
of red, pink, blue, green and deep yellow.
They are called "Fancy diamonds".
In the United States and around the world
colorless diamonds are graded on an alphabetical
scale, introduced by the Gemological Institute
of America (GIA). D, E and F color grade diamonds
may be referred to as "colorless"
or "rare white", D color is the
most expensive and very rare.
Weight:
Standard measure of a diamond's
size is carat(ct) weight.
Size alone is almost meaningless unless
you consider cut, clarity and color. A large
stone is not very valuable if it lacks brilliance,
purity and high-grade color . For the reason
that large stones are harder to find than
small ones, size does increase the value
of a good diamond.
No two diamonds are exactly alike, and a
reputable jeweler can help you weigh all
of the factors - color, cut, clarity and
carat weight.
