Custom Designed Jewelry

You often hear jewelers discussing the 4 C’s--Color, Cut, Clarity, Carat
Weight. Because diamonds are so valuable, in the 1940s and ’50s, The
Gemological Institute of America (GIA) developed the 4Cs along with the GIA International Diamond Grading System™ to objectively compare and evaluate diamonds. These terms are important for you to know when making your diamond buying decisions. You should also keep in mind that every diamond is as individual and unique as the person wearing it! Though the Four C’s are constant, the appearance of each diamond is not…just as with people— there are no two exactly alike. The more you learn about diamonds the more you will see they are even more brilliant and amazing than you ever realized…each with its own exceptional personality.

Diamond History

The Greek word "Adamas " means unconquerable and indestructible. This is the origin of the word Diamond. It is one of the most indestructible natural formations known to man. From this word and from the depths of the earth is derived The Diamond.

The 4 C's of Diamonds

1. Color - In the chaos of extreme temperature and pressure that first created diamonds, traces of elements such as nitrogen and boron could have been incorporated into the diamond’s atomic structure. This is the source of the tincture.

The first quality grade of a diamond to be judged is its color grade. Diamond can cover the entire spectrum of colors but the majority of diamond colors are yellow and brown.

Professional Definitions

Brilliant Cut - A beautifully cut round diamond that has 58 facets.

Carbon - The element that diamonds are made from.

Cutlet - The bottom facet of the diamond, this is usually very small.

Dispersion - This is the ability to create spectral colors as light exits the diamond.

Eye-clean - Refers to a diamond that to the naked naked eye has no visible inclusions or blemishes.
