Luckey's Jewelers Diamond Education

At Luckey's Jewelers we believe you should be informed about all the details of your diamond or the one you are shopping for. When you stop by to shop diamonds and engagement rings, we take special care and time to walk you through all of these details outlined by GIA.

A diamond’s value is based on the 4C’s. Cut, Color, Clarity, and Carat Weight. This grading system was developed by the Gemological Institute of America in the early twentieth century. Prior to that time, many different systems were being used to grade diamonds; today, the 4C’s method is the universal standard.


Cut refers to the angles and proportions of each facet and how it is placed. It is the only part of the puzzle that relates to brilliance and fire. Brilliance is defined as white light being returned back to the eye. Fire is defined as sparkle or the quantity and quality of spectral colors being returned to the eye. This diamond will dazzle your senses and amaze you with the quality of fire and brilliance.




The color of the diamond refers to its “body” color or tint. Most diamonds come out of the ground with a slight yellowish tint. Only the rarest diamonds are pure white or “colorless”. Diamonds are graded on a scale of D through Z. As the grade moves towards Z more yellow is visible. The human eye can begin to see a slight tint at about “I” color.

GIA Color Grades:



Clarity refers to the purity of the diamond, or the number and location of the inclusions in the crystal. An inclusion is described as an internal crystal or break in the diamond. Some of these are so small they are extremely difficult to see under a microscope, others are so large they can cause the diamond to break. The clarity grade is based on a trained observer viewing the stone under 10x magnification. The clarity grade ranges from Flawless (FL) to Imperfect (I). Generally, diamonds will be free of eye-visible inclusions until they hit a clarity grade (I).


Carat Weight

Carat weight is just that, it’s the weight of the stone and plays a large part in the stone’s value. One carat is divided into 100 “points” and weighs 0.2 grams. Additionally, a well cut diamond also has standard dimensions which can be seen in the actual-size picture below.
