Things to Look for When Choosing a Diamond

Diamonds are among the most precious jewels in the world, and for good reason. Few pieces of jewelry shimmer, sparkle, and shine like a diamond engagement ring or diamond necklace. Diamonds also make good investments for anyone looking to diversify their holdings and invest in loose precious stones. Regardless of why you’re buying a diamond in Rockville, MD, there are some very important things you should look for to ensure that you buy the highest quality stone for yourself or a loved one. These factors are collectively known as the “4 Cs of Diamonds,” and they include:


A diamond’s carat, or carat weight, is the measurement of how much a diamond weighs. All other factors being equal, diamond prices increase with carat weight since larger diamonds are rarer and more desirable by collectors. But diamonds of equal carat weight can have very different prices based on differences in any of the remaining Cs.


Although cut is often thought of as in terms of the diamond’s shape (round, emerald, pearl, etc.) it is actually a way of telling how well a diamond interacts with light. Higher cut grades deliver more intense sparkle and shine than lower quality cuts. Of all the factors, cut is the most complex and technically difficult to analyze.


A chemically “pure” diamond has no color, while lower grades of diamonds take on a yellowish color. The color scale begins with the letter D, representing colorless (and thus more valuable) diamonds and continues with the increasing presence of color to the letter Z.


A diamond’s clarity refers to the presence (or absence) of inclusions, blemishes, and other imperfections. Evaluating a diamond’s clarity involves looking at the number, size, and position of these characteristics and how they affect the overall appearance of the diamond. The less imperfections a diamond has, the higher its value.
