Diamond Guide

WeBelieve DiamondGuide

Buying a diamond is a very personal experience. Diamonds are bought to signify love, accomplishments, and milestones in a person's life. Unlike when you buy clothing or cars, the features of a diamond may not seem quite as obvious to you. We would like to change that.

We pride ourselves on accurate diamond grading and transparent diamond education. The more you know about your diamond jewelry, the more confident and comfortable you will feel when making your diamond jewelry choices. The Four Cs play an important role in determining a diamond's value and making your diamond unique. 


Shape

The shape is the stylistic outline of a cut diamond and is often confused with the cut itself. Choose a shape that you like based on your style, and you cannot go wrong. 

The following shapes are the most common:

 

 


Cut

The cut of a diamond refers to the placement of facets and their symmetry and proportioning. It has the greatest impact on a diamond's brilliance or sparkle. 

Before a diamond is cut, the location of inclusions and flaws, the natural coloration, and the original shape of the rough stone are studied extensively.

Most shapes have a standard brilliant cut consisting of 57 or 58 facets that reflect light in every direction. Other shapes (emerald, asscher, and baguette) have step cuts.

For optimal light performance, you want a diamond with a pavilion that is cut neither too shallow nor too deep. A deep cut sends more light out the sides. A shallow cut attempts to enlarge the surface area of the diamond, but it sends the light out the bottom. A very skilled cut alone can give you the benefits of the other three Cs.

At Ramsey's we believe in diamonds cut for maximum brilliance, not maximum size, and that low quality is never a good value. We always accurately describe and educate you about what you are buying.

Diamond Cuts
 
 
 

Color

Diamonds are graded on the amount of color they possess. The normal color range scale runs from D (colorless) to Z (light yellow). An absolutely colorless diamond is rare and therefore very valuable. Color becomes much harder to detect once a stone is set in a ring and is reflecting the colorful environment around it.

There are also colored diamonds outside of the normal range known as fancy color diamonds. They can be either natural or treated, and the rarest and most valuable natural colors are saturated pinks, purples, blues, and greens. They are graded on their color saturation and distribution. 

Diamond Color Scale
 
 

Clarity

A diamond is distinguished by its natural characteristics present on its surface (blemishes) or within the stone (inclusions). The clarity is judged by the number, size, and types of these features and is designated using a scale that runs from FL, defined as flawless, to I3, defined as inclusions visible with the naked eye. A flawless diamond is rare, comprising .001% of world diamond production.

 

 
  • Flawless (FL) - No inclusions or blemishes are visible to a skilled grader using 10× magnification
  • Internally Flawless (IF) - No inclusions and only blemishes are visible to a skilled grader using 10× magnification
  • Very, Very Slightly Included (VVS1 and VVS2) - Inclusions are difficult for a skilled grader to see under 10× magnification
  • Very Slightly Included (VS1 and VS2) - Inclusions are minor and range from difficult to somewhat easy for a skilled grader to see under 10x magnification
  • Slightly Included (SI1 and SI2) - Inclusions are noticeable to a skilled grader under 10x magnification
  • Included (I1, I2, and I3) - Inclusions are obvious under 10× magnification and may be visible to the naked eye. May affect brilliance and durability.

 


Carat Weight

A carat is a unit of weight, not surface area, used to measure gemstone size. One carat is equal to 200 milligrams, about the same weight as a paperclip. While the carat weight affects the surface area of a diamond, the dimensions (described in millimeters) will fluctuate noticeably among different diamond shapes and cuts of the same carat weight.

When comparing two diamonds, please note that just because one is twice the carat weight of another does not mean that it will appear to be twice the size. Additionally, a larger carat diamond with a poor cut can appear smaller than a smaller carat diamond with a better cut. 

Larger diamonds are rarer than smaller diamonds, so all other things being equal, one 1 carat diamond will be worth more than four .25 carat diamonds put together.
