Information About Diamonds

Knowledge is the key to a fair price in the diamond market. While you can depend on our Certified Gemologists and experienced estate buyers to carefully inspect the cut, color, clarity and carat of your diamond and to use our extensive information on the current diamond market to determine the highest price for your diamond, it can be helpful and interesting for you to learn a little more about diamonds and how we determine a price.



The cut of a stone is directly influenced by man, while the others are influenced by nature, and is one of the most important factors we consider when determining the value of your diamond. The “cut” is different than the shape – whether it’s an oval shape, a pear shape or an emerald shape, a well-cut diamond is always better able to reflect light. When a diamond is being cut, the flat surfaces are placed at angles designed to maximize the amount of light reflected and to increase the beauty of the stone.


The clarity of a diamond refers to how clear, or “clean” the diamond is. In it’s rough state, a dimaond is going to have imperfections, called “inclusions” (internal) and “blemishes” (external) – how severe the imperfections are determine the clarity of a diamond. A Certified Gemologist will grade the clarity of a diamond on a scale from “Flawless (FL)” to “Imperfect (I).”


The best color is no color at all. The color is graded from sparkling colorless white towards the more fancy colors. An absence of color allows light to be reflected and dispersed most dramatically as a rainbow of color. The color of a stone is rated on an alphabetical scale, from D (totally colorless) through Z (light yellow).


The weight of a diamond is expressed in carats. One carat is divided into 100 points, and stones that weigh less than a carat are sometimes measured in points (for instance, one half of a carat can be described as weighing 50 points or 0.5 carats). Carat weight refers only to the weight of a diamond, not its dimension. The higher the carat weight, the rarer the diamond, so a 2 Carat diamond is going to be more valuable than 2 1 Carat diamonds.


A Certified Gemologist will take into consideration all of the above aspects of a diamond when determining the value of a diamond.



The Shape of a diamond is a matter of personal preference – there is no particular shape that is more valuable than another.
