How to Find the Perfect Diamond | IW Marks Jewelers

A quality diamond is a girl’s best friend! When selecting the perfect diamond, it is important to understand what to look for. There are some things to consider when looking for that top quality diamond for your diamond ring, diamond pendant, or diamond bracelet. In addition to the 4 C’s (Color, Clarity, Cut, and Carat), choosing a reputable jeweler is also important.



The first step in selecting your diamonds is considering the color. Contrary to the name, your jeweler will evaluate the lack of color in your diamond to determine its value. The less that color appears in your stone, generally the more valuable the gem will be. Color is ranked from Grade D, completely colorless, to Grade Z, a yellow diamond. The shape of your diamond can also determine its color scale as well.


The clarity of your diamonds refers to the absence of inclusions and blemishes. When created in the earth, diamonds naturally will result in containing external and internal characteristics.  Clarity in diamonds ranges from Grade F for flawless, to Grade I that includes flaws. Your jeweler will examine your diamond under 10x magnification to determine its clarity.


A diamond’s cut does not actually refer to its shape, but rather how the cut interacts with the light. A round cut diamond is the most popular in the industry for its symmetry, sparkle, and timelessness. Choosing your diamond’s cut is considered one of the most important steps when selecting your diamond, so discuss with your jeweler to determine the right cut.


A diamond’s carat weight will measure the size of your diamond. A metric “carat” is defined as 200 milligrams. Each carat is subdivided into 100 ‘points.’ This allows very precise measurements to the hundredth decimal place. A jeweler may describe the weight of a diamond below one carat by its ‘points’ alone. A diamond’s price will increase with its weight due to larger diamonds typically being rarer and more valuable.


Choosing a Reputable Jeweler 

When you are ready to begin searching for the perfect diamond piece of jewelry, it’s also important to choose an experienced, reputable jeweler. Here are some things to consider when deciding where to look for diamond jewelry. Is your jeweler a member of a professional organization, such as Jewelers of America? Look at the number of years the jeweler has been in business and their history in the community. Does the jeweler have an onsite workshop, or do they send out the jewelry to be worked on elsewhere?
