Critical Facts for Purchasing a Diamond
Aug 24th, 2008 by Brad Morgan
The diamond is unique in the hierarchy of gems. Its elegance has been treasured since its discovery.
Whether you have experienced buying diamonds for engagement rings before or not, you may be unsure as to why one is worth $3000 while another one is only worth $300. What goes into determining the price of a diamond?
The physical weight of a diamond is referred to as its “carat”. The value of a diamond is directly proportional to its size. The larger the diamond, the more valuable it is, because larger diamonds are less common. Greater size makes the diamond more spectacular, and therefore increases the purchase price.
Carat size may push the price up, but only slightly if there is no clarity. Several facets determine clarity on both an internal and external basis. Internal aspects, dubbed inclusions, and external aspects, dubbed blemishes, all contribute to the overall clarity score.
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.
The appearance or absence of these imperfections is a result of how the diamond was formed underground over thousands of years. Since diamonds are often thought of as the symbol of perfection in our society, the more perfect they actually are under the scrutiny of a microscope, the more expensive they become.
Another important factor when evaluating the worth of a diamond is color. If certain gases were present beneath the earth when the diamond was forming, it may have taken on a distinct color.
The color of a diamond ranges from “D,” which is a complete lack of color, to “Z,” which is depicts a very noticable coloration. Diamonds are priced highly if they are deeply colored or are exceptionally clear. Hazy, off-colored diamonds are not considered a favorable item, so they are priced lower.
Lastly we need to understand the effect of the cut on pricing. The quality of the cut may not be as easy to evaluate for an inexperienced buyer as some of the other factors, but it is nevertheless a critical element as it gives the diamond its sparkle.
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.
Understand the 4 elements that make a diamond a special and precious gem: carat, clarity, color and cut. Knowing the difference between a dud and a dazzling diamond will be the difference between money spent poorly and money spent with wisdom.
