How To Choose The Perfect Diamond

Buying a diamond is one of the most important decisions a couple will make. Choosing the size and shape along with the style of the mounting are important, and very personal, choices. Understanding the characteristics that influence the brilliance, beauty and value of diamonds can make your buying experience more enjoyable and more fulfilling when you are looking for genuine diamond solitaire rings, diamond post earrings, and more.

Diamond are like people-no two are ever exactly alike. Very subtle differences in the internal and external characteristics of each stone, along with subtle variations in color and cutting proportions, have a measurable effect on the value of two diamonds which may appear to be similar.

Start with a good jeweler, one who’ll take the time to help you through the 4 Cs-cut, color, clarity and carat weight. Understanding the language of diamonds will put you more at ease in making your selection.

The 5 Cs


Cut actually means two things: the shape of the diamond (round, marquise, pear, oval, heart, emerald, princess, radiant, etc) and the proportions of the stone. When a stone is cut to good proportions, light is reflected from facet to facet, then dispersed through the sparkle, brilliance and fire of the stone.


Most diamonds look colorless. But there are many subtle shade differences that range from colorless to yellow/brown. Diamonds are graded on a color scale that ranges from D (colorless) to Z (yellow/brown). Diamonds with no hint of color at all are extremely rare and are therefore, most valuable. Most gem quality stones appear to be colorless, but they usually have at least a hint of color.


Almost all diamonds contain a combination of internal and external characteristics called inclusions and blemishes. Normally, they are too minute to be visible without powerful magnification. Some are even so small they require great skill and time to locate. The number, type, location, visibility and color of inclusions determine a diamond’s clarity and may influence its value.

Carat Weight

Like all precious stones, the weight or size of a diamond is measured in carats. A one carat stone is equal in weight to one hundred smaller units called “points” Therefore, a fifty_point diamond, for example, is the same as a half carat. Carat weight is the most obvious factor in determining a diamond’s value, depending on the quality of its cut, clarity and color.

Diamond Enhancement for Color or Clarity

Diamonds can be colored to reach a variety of hues. Extreme heat and irradiation permanently enhance certain innate color properties, allowing them to display their hues in more brilliant array. At SuperJeweler.com, black diamonds, blue diamonds, brown diamonds and yellow are enhanced in this way for the most consistent color at the best possible price.

Diamonds can be clarity enhanced by utilizing special materials to fill the fracture of an included diamond. SuperJeweler sells clarity enhanced diamonds and indicates this by in the text of the diamond description. Clarity Enhanced diamonds may require additional care.

Ethical Sourcing

The SuperJeweler.com Conflict-Free Diamond Policy
SuperJeweler.com, along with the global diamond industry, has a zero-tolerance policy toward conflict diamonds. Through measures such as the Kimberley Process, which tracks diamonds from mine to market, the industry in partnership with the United Nations, governments, and non-governmental organizations, polices diamond exports to prevent the trade of illegal diamonds.
