Know Your Diamonds
For centuries, diamonds have symbolized love and romance conquered hearts and marked special occasions like anniversaries. Everyone desires a diamond, yearns to own one and waits to flash it once its theirs to cherish.
Wearing a diamond is like donning a piece of history borne 100 million years ago. The beauty of a diamond is lent by its durability to withstand and be produced in hot and cold extremities. Sifting mountains of rock, in the harshest of climates, produces rough diamonds. However, such is the power and the elusive property of the diamond that a ton of diamond bearing rock may only yield a paltry half carat of diamonds. While the earth can squeeze carbon into the hardest substance known to man, the dexterity of the human touch can bring out the beauty and luminosity that is the inherent attribute of a diamond.
Every diamond has its own unique identity and though every diamond is cut and polished to rigorous standards, each has its tiny quirk in the form of a bubble, line or speck almost invisible to the naked eye. Among millions of carats mined each year, there only a few hundreds that are truly flawless. The rarest of these are among the most expensive as well. The cut of a diamond affects its brilliance. While a traditional cut radiates incandescence, the modern ideal cut sparks off a rainbow of colours. Both can be dazzling and can be chosen as per individual preference.
Certification
Certification for a diamond is like its proof of identity, detailing its unique characteristics. The certificate includes measurements, grades, color, cut and clarity as well as the little quirks it might have. You may also receive documents from other recognized certifying bodies. Look for names like the American Gem Society, Belgium High Council, International Gemological Institute and European Gemological Laboratory.
Shape
The shape of a diamond is determined by the configuration of its girdle. The girdle is the largest perimeter that outlines the diamond and separates the top from the bottom. If you look at the girdle from the top it will indicate to you the diamond’s shape– round, oval, drop, marquis etc. Shape will influence how a diamond is cut for maximum brilliance.
Knowing your diamonds is important before you buy them.
The 4 Cs of a Diamond Cut, color, clarity and carat
Cut
The cut of a diamond shows off its brilliance and luminescence. Cut is the most critical of the 4 Cs of a diamond and is responsible for brining out its beauty. Although several terms are used to describe the quality of the cut, it is essential to remember that very good diamonds reflect 90% of the light entering from above and poor quality diamonds reflect only 40% of the light. Proportion plays a key role in the cut of a diamond. A shallow cut diamond reflects light downward from its base. A diamond cut too deeply will emit light from the side of its base. Ideally cut diamonds, and therefore more perfectly proportioned stones, reflect most of their light through their table or top surface. This quality is the most prized and costly. Diamonds can be cut into a variety of shapes Emerald cut, heart and marquise, oval, pear, princess and round
Color
The absence of color is the mark of a good quality diamond. The purest of diamonds have no colors to conflict with their luminescence. The only exceptions are certain fancy colored diamonds with a hue of blue or pink are rare and extremely precious. Diamonds are graded on the basis of color. The Gemological Institute of America uses the letters “D” through “Z” to rank diamond color. Blue white diamonds, considered absolutely colorless, carry a top rating of “D” while those on the bottom of the rung bearing a yellowish hue carry a “Z” rating.
Clarity
Clarity signifies the inner beauty and appearance of the diamond. Clarity has its own measure while determining the value of a diamond. Nearly all diamonds have their own quirks of bubbles, specks and lines giving every diamond their own inner signature. The clarity scale accounts for these microscopic imperfections and diamonds with as few quirks are the rarest and costliest.
Carats
Diamonds are measured in carats. One fifth of a gram equals one carat. Larger diamonds, always rarer than smaller ones, are not priced proportionately higher. Owing to its rarity, a two-carat diamond will cost more than two one-carat stones of equal quality. Small diamonds are weighed in “points” equal to 1/100 of a carat and priced accordingly. Obviously then, a diamonds measure increases with the number of carats.
