Diamond, one of the rarest materials on the planet, is the only gem made from a single element: carbon, in its purest form. Each diamond is the result of an extraordinary journey, from hundreds of kilometers below the surface of the earth, going through enormous pressure and very high temperatures, to become the most coveted jewel in the world.
Poem by Rubén Darío
Can a drop of mud
on a falling diamond;
can also be done this way
its glow darken;
but even though the whole diamond
is full of mud,
the value that makes it good
will not lose an instant,
and must always be diamond
no matter how much the silt stains it.
The diamond-bearing rock, kimbertlite, is brought close to the surface by volcanic eruptions of deep origin. The magma for such a volcano must originate at a depth where diamonds can be formed, about 150 km. This is something that happens rarely.
Once diamonds have been brought to the surface by magma in a volcanic chimney, they can be eroded and distributed over a large area. A volcanic chimney that contains diamonds is known as a primary source of diamonds.
The name of diamond comes from the ancient Greek “adamas” which means unbreakable, indomitable and invincible. Diamonds have been treasured as gemstones since they were discovered.
In the modern age, the mere mention of the word “diamond” continues to evoke images of elegance, style and glamor. The diamond shines and dazzles, symbolizes purity and strength, celebration, the essence of love and romance. A diamond is ideal for everyday wear, due to its resistance to scratches, which has perhaps contributed to its popularity as the gem of choice in engagement and wedding rings.
The diamond is exceptional and distinctive. A miracle of nature. No two diamonds are the same. Although all diamonds have certain characteristics in common that allow experts to compare and evaluate them.
There are four main factors to consider when judging the quality and value of a diamond. Expert gemologists use state-of-the-art equipment in order to evaluate all these characteristics.
It is often confused with size, even though it is currently a measure of weight. A diamond cut can make it appear larger or smaller than its actual weight.
One carat is equivalent to 200 milligrams and can be divided by 100 points. A 0.75 carat diamond is the same as 75 points or 3/4 carat of the diamond.
The term carat is a derivative of the word carob. The seeds of the carob are surprisingly uniform in their weight, they were used as a reference for the weight of the diamond in ancient civilizations. One carob was equivalent to one carat.
When diamonds are mined, large gems are discovered much less frequently than smaller ones. Diamond prices increase exponentially with karat.
Cut refers to the angles and proportions that a skilled carver creates and transforms into a polished diamond. Cutting a diamond requires great skill and training. The cutter will need to polish the small surfaces known as facets on the rough diamond.
A well cut diamond will reflect internal light from one facet to another, scattering it across the top of the stone.
The cut also refers to the shape of the diamond, the most common are the following: round, which is known as brilliant cut, emerald, heart, baguette, pear, oval, princess.
The Purity (or Clarity) of the diamond:
The clarity of a diamond is a measure of the presence or absence of inclusions visible or not visible to the naked eye or with a 10x magnifying glass. The lighter a diamond is, the less light it deflects and the more light it reflects and, consequently, it is scarcer and more valuable.
Diamond clarity has many significant factors that must be considered when certifying a diamond, for example: size of defect, location, number of defects, if external or internal, etc …
The imperfections can be foreign materials such as: other crystals, air particles within the diamond, or internal imperfections, such as small cracks within the stone. It is considerably rare to find a perfect diamond – one that does not show any stains, lines or cracks.
The inclusions of a diamond significantly influence its value, but in most cases they will not disturb its beauty. They give it character and print originality.
In fact, most inclusions are not visible to the naked eye, requiring a magnifying glass. Thus, whether you purchase a flawless diamond or one from the VS category, the appearance at a glance will be the same, especially considering that it will be set in a jewel. Only for diamonds with clarity “I” can you begin to appreciate the difference in brilliance when compared to a high purity diamond “Flawless“.
Therefore, in general, a diamond with VS clarity is sufficient to show off in a jewel, and institutes an excellent compromise of quality and price.
The color of a diamond measures its degree of transparency and influences its beauty and price.
Most quality diamonds used in jewelry are colorless or nearly colorless, sometimes tinged with yellow or brown. Among the rarest are the colors D, E and F on a scale that goes up to Z.
Gemological laboratories issue diamond certificates where their color grade is included. They use special teams to compare each diamond to a “master” set of diamonds.
The gemological certificate is the best guarantee to confirm the real color of a diamond.
The normal range of colors in the diamond
The GIA (American Gemological Institute) developed in the 1950s a gradation scale for diamonds in the normal range of colors . This scale ranges from D (totally colorless) to Z, yellow or light brown. Brown diamonds darker than K are engraved using that letter and a descriptive phrase. Diamonds between K and M are graded according to the phrases Very weak brown , N to R as very light brown and S to Z as light brown. An S diamond is called S-light brown . Diamonds beyond Z fall into fancy colors.
The whiter a diamond is, the greater the amount of light it can receive. The light penetrates the table of the diamond, when it is reflected in its facets, it comes out again in the form of sparkles and sparkles. What is called fire.
Colorless diamonds are more rare, which increases their price significantly.
And for today ends this amazing journey with the diamond from the depths of the earth to this special moment when you read me.
