The 5 C's of Diamonds

All diamonds will be sold below published wholesale price. We uphold high standards of quality, and only show well-cut diamonds. We also offer a lifetime upgrade policy on all the diamonds we sell when exchanged in their original condition.

For example, if you purchase a 1.00 carat diamond engagement ring and want to upgrade on your 10 year wedding anniversary, we will credit the full amount you paid for the 1.00 carat towards the purchase of a larger diamond. Similarly, you can upgrade diamonds set in stud earrings as well.

In order to recognize and fully appreciate the inherent beauty of a diamond, you first need to compare and evaluate diamonds side by side with your jeweler. We do this in a relaxed atmosphere, spending time with you and educating you in the process. Choosing your own diamond should be a pleasant experience and one to be remembered. You can trust our experience and ability to locate a selection of diamonds that offer the ultimate combination of the "Five C's" for you.

1. Cut

The single greatest determinant of a diamond's fire and overall beauty is the precision with which it is cut. In order to maximize a diamond’s brilliance, a master craftsman must precisely align each of the stone's facets and angles in exact geometric relation to one another. The cut gives each diamond its unique sparkle and brilliance by allowing a maximum amount of light to enter and reflect back out of a diamond. When a diamond is cut too deeply or too shallow, light spills out of the side or bottom. Thus, poorly cut stones will exhibit less brilliance and will be less valuable.

An "ideal" cut diamond has been shaped to the optimum proportions for maximizing the diamond's dispersion of color and brilliance. To achieve this, much of the rough diamond may be lost in the cutting process. This is why less than 1% of all diamonds are cut to ideal proportions. Since the cut is the most critical variable affecting the diamond's value, It is important to find a jeweler you can trust to advise you of the quality of a diamond's cut.

2. Color

A diamond's color is its second most important factor in creating its brilliance. A diamond's beauty and value will usually dramatically increase with a higher color grade. The spectrum ranges from D (totally colorless) to Z (a light yellow). The majority of diamonds we sell at Teel’s are in the EFGH range, although we can also provide a wider spectrum of colors, including fancy and fancy-intense yellows.

Do keep in mind that there are several nuances in the diamond selection process. For example, a very well cut diamond will often disguise a certain level of color by increasing the amount of white light returned to the eye (brilliance) and dispersion (the presence of spectral colors in the light seen by the viewer).

3. Clarity

Virtually all diamonds contain identifying characteristics called inclusions or imperfections. These are "natures fingerprints" or birthmarks, most of which are not visible to the naked eye. Under the scrutiny of 10X magnification, these inclusions appear as tiny crystals, clouds, or feathers. The number, color, type, size and position of surface and internal birthmarks affect a diamonds value. Major inclusions can interfere with the path of light that travels through a diamond, diminishing its brilliance, and therefore its value. Minor natural birthmarks do not affect the beauty of a stone, but they definitely affect its price. The grading scale begins with flawless (FL) and continues to Imperfect (I-3). Keep in mind that inclusions are visible to the naked eye and the I level. We generally recommend diamonds in the SI2 to VS1 range or better.

4. Carat

A diamond's size is measured in carat weight. A carat equals 1/5 of a gram, and is divided into 100 equal portions, called "points" (a quarter-carat diamond can be referred to as .25 carat, or 25-points). As diamonds increase in size, the price increases exponentially (not arithmetically).

5. Cost

The last and 5th C represents the cost of the diamond to you (very important!).
