Diamonds reside in a prestigious class all
their own, with a history that dates back to the 15th century. The
first recorded diamond engagement ring was bestowed to the fiancée
of an Austrian prince in 1477. From this time forward, diamonds have
been the representation of love and promise of marriage. Over the
years, people began to purchase diamonds to celebrate important
events in their lives such as anniversary, marriages, achievements,
and engagements, or to simply reveal an expression of love.
Technological advances have allowed for accurate cutting, polishing
and finishing of diamonds. These improvements are responsible for
the vast number of styles and cuts that are on the market today.
This wide variety of gems and price ranges will easily fulfill
everyone’s taste and budget.

The 4C’s
The four
Cs are defined standards of comparison that allow for the buying and
selling of this precious gemstone. The Gemological Institute of
America (GIA) created a universally accepted diamond grading system
based on the four Cs of the diamond: carat weight, color, clarity, and cut.
Carat weight Refers
to the unit of weight used for diamonds and other gemstones
articulated in carats. 100 points equals to 1 carat.

Color is defined by
the amount of body color in the diamond. The grades for color
indicate the amount (saturation) of color and range from colorless
(D) to very saturated (Z). Colorless diamonds are rare and most
diamonds have a very slight hint of yellow, brown or gray. The
increased popularity of diamonds with some body color, has given
rise to the prettier brown shades being sold as “champagnes” and
“cognacs”. Diamonds that have a body color other than light yellow
or light brown (for example: pink, red, blue, green, or orange) are
referred to as “fancy” diamonds and are graded differently. GIA

Clarity defines the absence or presence of external (blemishes)
characteristics and internal (inclusions) features under the jewelry
industry standard of magnification, 10 power (10x). The quantity of
inclusions along with their size, color, relief and location
determines a diamond’s clarity grade. These characteristics also can
impact a diamond’s durability and beauty. Clarity grades range from
flawless (FL) to heavily included. Flawless diamonds are very rare
and practically all diamonds have inclusions. Every diamond is
unique and its inclusions are actually identifying characteristics.
SI (slightly included) and I (included) clarity grades are less
rare, commonly used in jewelry and more affordable.

Cut has two
implications. The term cut sometimes refers to the shape of a stone,
for example: round, oval, pear, marquise, heart or emerald. More
commonly and importantly, cut or “make” refers to a diamond’s
proportions, the correlation between its size (carat weight), shape,
and cutting angles. Finish describes a diamond’s facet symmetry and
polish. Cut is important because it impacts a diamond’s ability to
redirect light through it and back to your eye. Cut is the main
reason why some diamonds look lively and others appear dull or
watery. Brilliancy or sparkle refers to the flashes of hite light
reflecting off a diamond. Dispersion or fire is the term that
describes the flashes of rainbow colors that diamonds have. The cut
of a diamond is essential in achieving the maximum light return and
directly influences the diamond’s beauty. Historically diamonds were
purchased by a man for a woman, either as a gift or to symbolize a
wedding engagement. However today, with a majority of women in the
workforce, they are a popular self-purchase item.
