Diamond Education
The diamond is the best known and the most heavily marketed gemstone. Like
graphite Lonsdaleite ("hexagonal diamond"), and the fullerenes, a diamond is an
allotrope of carbon
and, no matter what its size, each diamond can be considered to be a single
molecule of carbon. [Continued...]
Cut refers to the shape and proportion of a diamond. Diamonds may be cut in a
wide variety of shapes but the most popular are round, oval, marquise, pear,
emerald, radiant, princess, and heart. While other diverse cuts are available on
the market, the round brilliant cut is still the top choice. [Continued...]
Carat - the unit of measure originates from the word "carob". The Carob tree is
an evergreen tree native to the Mediterranean region and it is believed that the
seeds were the original "carat", since their size and availability made them a
perfect tool to weigh diamonds. A carat is equivalent to 200 milligrams or 3.086
grains troy ounce and is divided into 100 points. [Continued...]
Most Diamonds contain inclusions. Sometimes they are incorrectly referred to as
"carbon spot". In reality they can be a myriad of things from other minerals
such as carbon or even a garnet. There can also be minute fractures within the
stone. Whatever they are, they are the internal characteristics of the stone.
It is what makes each diamond unique. You should learn to recognize the
"birthmarks" in your stone as they are an easy means of identification. [Continued...]
In the late 1950's GIA (The Gemological Institute of America) introduced the
colour grading system that is used today. The GIA grading system replaced grades
such as Top Wesselton and Capes and is internationally accepted. In most cases,
unlike all other gems, it is the absence of colour that makes the stone more
valuable. [Continued...]
The Valuing of diamonds requires an assessment of each of the four Cs (cut, colour, clarity and carat weight).
But a fifth factor-fluorescence often plays a role in the pricing and marketability of diamonds. [Continued...]
Coloured diamonds are rare. Therefore availability is usually on a waiting list basis.
