There is no gemstone in the world quite like a diamond.. Diamond formed by nature, the average diamond is 3.3 billion years old. A diamond is a testament of endurance and strength and not surprising the ultimate symbol of love. If you're shopping for a diamond chances are. You're celebrating an exciting, an emotionally charged moment in your life.
As you sit down with your favorite trusted jeweler, you probably have a lot of questions and concerns like how can I be sure that what I'm purchasing is a real natural diamond? How do I know if the diamond is being treated ones.
You may also wonder about the methods used to assign value to these unique and beautiful stones. You know you want to buy a piece that speaks to your heart but you also want to make a smart purchase. So where do you begin?
The key to understanding diamond is to understand the four attributes that all diamonds have in common. These four factors color, clarity, cut, and carat weight are known as the 4Cs.
When it comes to diamonds, the less color the higher the grade. The GIA color scale classifies diamonds from “D” colorless to “Z” light yellow or brown.
Each letter grade represents a range of color and is a measure of how noticeable a color is. True colorless diamonds are very rare. Most diamonds used in jewelry are nearly colorless with tint of yellow or brown.
To provide a universal basis for color comparison most of the gemological laboratories meticulously assembled a set of master stones representing the color grades on the color scale. And diamond’s color grade determined by comparing each diamond to a master set that has been assembled by carefully matching diamonds to the original sets.
Because diamonds form under tremendous heat and pressure, it is extremely rare to find a diamond with no internal or surface reaching inclusions. Inclusions or a byproduct of its formation and actually helped gemologist separate natural diamonds from synthetics and look-alikes
The GIA clarity scale includes eleven clarity grades ranging from flawless (FL) to I3. Flawless indicates that there are no inclusions or blemishes visible at ten times magnification.
A grade of I3 is for diamonds with inclusions are obvious to the naked eye. Diamond graders use a 10 times magnification loupe or microscope to see and plot the inclusions.
Since no two diamonds are exactly alike, this unique plot helps identify a particular stone. During this step, graders also look to see if there's any evidence that our diamond was treated to improve its clarity and any treatment will be noted on diamonds reports.
The GIA cut scale is used for round brilliant cut diamonds and consists of five grades ranging from excellent to poor.
You may think of cut is the shape of a diamond like square cut or round. However there was much more to cut than the basic shape. How a diamond is cut and polished directly affects the amount of spark and brilliance that comes off a stone when interacts with light. How light strikes the surface, how much enters the diamond, and how and in what form light returns to your eye. A polished diamonds proportions affected its light performance which in turn affects its beauty an overall appeal. Since there is no single set of proportions that define a well cut diamond. Diamond cut grade needs to be determined by factoring in a range of parameters including its culet size, girdle thickness, polish and symmetry.
One carat equals 200 milligrams or one-fifth of the gram in weight. Larger diamonds are rarer than smaller diamonds so all other factors being equal a single one carat stone would be worth more than four quarter carat stones put together. However, the value of a diamond is determined by considering all four Cs. So bigger is not always better.
Whether you're celebrating the past, or getting ready to leap into the future. There is no better way to commemorate this important moment in time than with a diamond. A symbol of timeless itself. The active choosing your diamond should be exciting and enjoyable. Just keep all the four Cs in mind “color”, “clarity”, “cut” and “carat weight”. And be sure to always ask your jeweler for your diamond report, your ultimate assurance of your diamond's quality. What you've chosen is rare and breathtakingly beautiful. You've chosen a diamond and you've chosen well
