The diamond is unsurpassed in the hierarchy of gems. Its elegance has been loved since its discovery.
If you are confused about why some diamonds are so much more expensive than others, you are not alone. Why oh why can one diamond engagement ring be worth $8000 and another one that doesn’t look that much different to the naked eye be worth only $2000?
The grading system for diamonds is based upon four different elements. Firstly, size will play a large role in the price. This is referred to as the “carat weight,” and it is determined on a 100 point scale. The larger the carat weight, the higher the value.
After carat weight is obtained, the next aspect that can cause price deviation is the clarity. You can determine the clarity of a particular diamond by a number of features. The term inclusions refers to imperfections inside the diamond, while blemishes refer to imperfections on the surface.
The quantity, type, location, measurement, and tint of its inclusions, or internal facets, as well as its blemishes, or features on the surface, all factor into the clarity. The clarity ranges from the rank of ‘pure,’ meaning no flaws, to ‘heavily included,’ meaning that it is seriously damaged.
Therefore the more severely included a diamond is with crystals, feathers, or other types of internal and external flaws, the lower its value. These deformities are due to the cooling process of the diamonds against other materials. Clarity is highly prized, especially in larger carat diamonds where the imperfections are more detectable.
Color is the next factor that determines a diamond’s overall value. If possible, a diamond should be as clear as water, but this is not always the case. Colors from other gases and minerals around during the time of the diamond’s formation may have altered its clean appearance and left the gem tinted.
There is a scale of coloration that ranges from “D,” where no color is present, to “Z,” where color is easily visible. There is a spectrum known as “beyond Z,” where the colors are rich and vibrant within the diamond and are referred to as fancy colors.
The cost of a diamond is also determined by one final factor, the cut. The cut of a diamond gives it the ability to glitter by reflecting the light back out in very precise ways.
To view a diamond from the point of view of the cut is to investigate whether or not it has any ‘fire’. Like the other criteria for grading, the cut has it’s own grading scale that goes from excellent to irregular. If the diamond doesn’t knock your socks off then it likely has not been cut very well.
Diamonds are rare, but they are not equally special. Understanding the four important C’s of carat, clarity, color and cut that represent the value of a diamond will lead you towards making a better buying decision.
