Buying a Diamond

Buying a diamond might seem like a daunting task at first.  There’s a lot to learn before making such an important purchase. Shane Co. believes that information is power, and is committed educating people on the proper way to evaluate diamonds so they are empowered to make an informed decision. Here are the essentials you should know (you can also see an infographic on buying a diamond).

Diamonds are graded on four characteristics, commonly known as the 4 Cs: Carat, Clarity, Color and Cut.

Diamond Lab Reports

Diamond grading is a subjective process and there is no one way to grade any single diamond. If you wish to purchase a diamond using the diamond lab report (or ‘cert’) for reference we recommend you focus on color, clarity and carat.

Carat

Diamonds are sold by carat (ct.) weight. For two diamonds of equal quality, the larger the carat weight, the more rare and valuable the diamond.

Clarity

Clarity refers to the degree to which the diamond contains naturally occurring inclusions. The clarity grades range from F (for flawless) to I3 (with visible inclusions). Inclusion can be thought of as the fingerprint of your diamond.

Cut

Of the four Cs, cut has the greatest influence on the diamond’s sparkle, brilliance and fire. Cut refers to the number, placement, angling and shape of the diamond’s facets. The facets function as prisms, capturing and reflecting light inside the diamond.

A well-cut diamond reflects and refracts the maximum amount of light back through the top of the diamond to your eye, creating lots of sparkle. A poorly cut diamond reflects light out of the sides or the bottom of the diamond, giving the stone a dull and lifeless look.

Color

The color grade refers to how much the diamond’s color deviates from a true absence of color. Color grades are based on letters of the alphabet and a range from D (colorless) to W (light yellow).

Understanding Subjectivity

It might surprise you to learn that diamond grading is far from an exact science. There are several major gemological laboratories and the grades each lab assigns to each diamond it certifies are the opinions of the individual at the lab who graded the diamond, based on the lab’s own subjective grading standards.

Some labs are looser or stricter when grading cut, color and clarity, and some are more consistent in applying their grading standards than others. So if different labs were to grade the exact same diamond, they would typically give the diamond different grades.

The Gemological Institute of America (GIA) is known for having the strictest grading standards of the leading labs and is also the most consistent. The European Gemological Laboratory International (EGLI) generally has looser grading standards and consistently grades diamonds 2 to 2.5 grades higher than GIA.
