Choosing a loose diamond is a very special and important decision. We are here to make the process simple to understand and to give you the confidence to make the best decision possible.

There are many variables that determine the value of a diamond. At Carreras we can help you understand the 4 C’s of diamond grading while adding a 5th C for the confidence to make an informed purchase. Many diamonds are sold today with an outside laboratory’s diamond grading report. These reports alone cannot tell you what your eyes and our microscopes can see. It is important that you have an experienced professional explain the diamond grading reports as they may vary in accuracy. At Carreras we carry many diamonds that are accompanied by AGS or GIA grading reports. We can personally go over the report with you to help you understand the grading scales. By viewing more than one diamond, side by side, you can visibly compare how different they are.


At Carreras, we teach the 5 C’s of Diamonds: Cut, Color, Clarity, Carat, & Confidence

Of all the C’s, cut has the greatest effect on a diamond’s beauty.
diamond_cut_diagram Cut is also the only characteristic of a diamond that is not determined by nature. In determining the quality of the cut, the grader evaluates the cutter’s skill in the fashioning of the diamond; the more precise the cut, the more captivating the diamond is to the eye. Our loose diamonds have been graded for Light Performance, Proportions and Finish, then given a final Cut Grade.

Too Shallow: Light is lost through the bottom, causing the diamond to lose brightness
Too Deep: Light escapes out the sides, causing the diamond to appear drab and dark




Gem-quality diamonds occur in many hues. In the range from colorless to light yellor or light brown. Colorless diamonds are the rarest. Other natural colors (Blue, Red, Pink) are known as fancy, their color grading is different from white diamonds.



Natural diamonds are formed as the result of carbon exposed to tremendous heat and pressure deep in the earth. This process can result in a variety of internal characteristics called inclusions and external characteristics called blemishes. Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone. Diamonds without inclusions or blemishes are rare and while no diamond is perfectly pure, the closer it comes, the higher its value becomes.

Diamond Clarity Grades



The carat is the diamond’s physical weight measured in metric carats. One carat equals 1/5 gram and is subdivided into 100 points. This allows for a very precise measurement to the hundredth decimal place, A diamond may be described by its ‘points’ alone. A diamond that weighs 0.25 carats can be described as twenty-five points or a quarter of a carat. Diamond weights greater than one carat are expressed in carats and points. A 1.09 carat stone would be described as one point zero nine carats or one hundred and nine points. Because there are more small diamonds found in nature than large diamonds, the price per carat for larger diamonds is higher. Carat weight is the most invariable of the 4 C’s.

At Carreras we carry a wide selection of diamonds, in many shapes and sizes from a wide variety of sources, ensuring you the best value for your budget.

Cleaning and Storing Your Diamond Jewelry

For a quick cleaning, soaking your diamond ring in a solution of mild liquid detergent and water can be effective. Our Carreras jewelry cleaner will keep your diamonds sparkling clean, and we always welcome you to bring in your diamond jewelry to have us inspect and clean it for you. We recommend that all diamond jewelry is stored in soft cloth pouches when not being worn to prevent the diamond or diamonds from scratching or dulling other jewelry. We are happy to give you a Carreras pouch with each purchase.
