The 4 C's
A diamond ring is a substantial addition to your precious Jewellery collection, so it is important that when buying your piece you get value for money, and importantly that you understand what you are buying.
Diamonds are appraised in a rating system called the 4 C's standing for Cut, Carat, Color and Clarity.
Below is a guide for you to refer to when selecting your next precious purchase.
A diamond's cut is expressed in terms of proportions and finish. Proportions describe the angles of inclination and proportional relations between the various parts of the stone, whilst finish is mainly concerned with the symmetry deviations and positioning of the facets. A diamond's cut is its most important feature. A poorly cut diamond will "leak" light out the back, diminishing the stones value. A good cut will magnify the brilliance and liveliness creating a well performing diamond.
Carat refers to the Diamond's weight. One carat equals a fifth of a
gram. The total carat weight of a diamond contributes considerably to
the value of the piece.
Diamonds come in a variety of colors. White diamonds are the most common
and the most popular. A perfectly white diamond should be crystal
clear. The lighter the tint of yellow or brown, the more rare and
Clarity refers to the appearance of internal characteristics; the fewer
the number the higher the grading. Nearly all diamonds contain
inclusions or flaws that diminish the stones brilliance. The highest
clarity grading is expressed as a "loupe clean"
and is completely free of inclusions when viewed by an experience
grader through a 10x loupe (magnifier). The lowest clarity grades
possess inclusions that are visible to the naked eye.
Diamond Carat Weight Key Points
Carat is specifically a measure of a diamond's weight, and by itself may not accurately reflect a diamond's size.
We tend to evaluate diamond size by viewing it from the top because that is how diamonds are presented to us when set into a ring.
To understand diamond size, carat weight should be considered in conjunction with two other criteria:
Distance in millimeters across the top of the diamond.
Diamond's cut grade.
As the name suggests, carat weight specifically refers to a diamond's weight. However, much as a person's weight does not necessarily correlate with height, carat weight, by itself, may not accurately reflect a diamond's size. To gain a precise understanding of diamond size, Craig Gems and Fine Jewelry recommends considering carat weight with two other characteristics: 1) the distance across the top of the diamond measured in millimeters, and 2) the diamond's cut grade.
It is important to measure the distance across the top of the diamond as this is how we view a stone when set into a ring.
A diamond's cut grade should also be considered because, as we noted in the cut grade section, when a diamond is cut with the proper proportions, the maximum amount of light (or sparkle) is returned out of the top of the diamond. Thus, when a diamond is well cut, the light reflected out of the top makes it appear larger. In addition, much of the weight of a poorly cut diamond, for example, may be "hidden" in the base of the diamond, making the diamond appear smaller than its carat weight would imply.
Colored Gemstone Enhancement Processes
There are many methods of enhancing colored gemstones. We describe the most common enhancements below. For more information on colored gemstone enhancements, see the American Gem Trade Association's Gemstone Information Manual.
The application of heat to enhance the color and/or clarity of gemstones has been a common practice around the globe for centuries. It is part of the standard polishing and finishing process for many colored gemstones. As such, it is accepted by the jewelry industry and the American Gem Trade Association. The enhanced color and/or clarity of heat-treated gemstones is permanent.
The filling of a gem material with an oil, wax, glass, resin or other material, colored or colorless, to improve appearance. This process began centuries ago by gemstone merchants who found that immersing emeralds in oil or waxes made them look clearer to the unaided eye. This practice continues today with many colored gemstones.
The use of wax, resin or oil applied to the exterior of a porous colored gemstone to protect the natural substance, and to improve sturdiness and appearance.
The application of chemicals or other elements to lighten or enhance color consistency.
The act of adding coloring agents so that they permeate a colored gemstone to enhance or alter color.
The alteration of a gemstone's color through the use of radiation. This is often followed by a heating process. The enhanced color of irradiated gemstones is permanent.
New and Future Technologies
Techniques for enhancing colored gemstones, either detectable or otherwise, are continually being developed. These may be difficult, or in rare cases, impossible to detect, even for the most sophisticated laboratory. Craig Gems and Fine Jewelry will continue to work with industry groups and gemological experts who are committed to the identification and disclosure of new and future techniques in order to maintain our stringent quality standards.
