What is a Diamond? Part One

What Is A Diamond?

A Diamond is a rare precious gem and one of the oldest minerals, having been formed deep within the bowels of the earth over billions of years! Born from pure carbon, the diamond is clear crystalline and the hardest naturally occurring substance. The diamond’s high brilliance, rarity, and hardness has captivated and enticed the imagination of human civilization ever since the 4th century BC when the ancient Hindus first prized the diamond as a rare gem calling it vajra or “thunderbolt.” Because of the natural properties of a diamond, people around the world have come to associate this beautiful stone with timelessness, strength and beauty.

Value of a Diamond | Color, Clarity, Cut, Carat

Temperature, pressure, and the earth’s shifting layers can all radically change the formation of a diamond, making it impossible for any two diamonds to be alike.  Diamonds can be individually distinguished by  the 4 C’s, otherwise known as Color, Clarity Cut, and Carat.  These terms are an essential part of the makeup of each individual diamond.

Diamonds of the highest value are pure colorless brilliant gems with transparent color, high clarity, excellent cut, and a large carat weight; these diamonds are very popular for use in engagement rings and bridal jewelry.

Diamond Color

When we think of diamonds, what immediately comes to mind are white diamonds, but diamonds can come in any color of the rainbow! Mother Nature provides a variety of naturally colored diamonds known as fancy diamonds. Naturally colored or “fancy” diamonds come in champagne, chocolate, and yellow tones as well as lavender, pink, red, blue or green, to name a few. Some hues, like rare pink or blue diamonds, are particularly difficult to find.

Diamond Color Grade Chart

Most colorless (white, transparent) diamonds have a touch of brown or yellow tint in them, and it is the amount of tint they contain which determines their value. The less tint the higher the value! Diamonds are graded on a scale from D to Z, a system developed by the Gemological Institute of America. “D” rates as the highest grade of color, signifying an absolutely transparent, colorless, very rare gem.

Many diamonds look glamorous no matter what their grade is, since a diamond’s value is primarily based on the skill of the jeweler who cuts it. Ultimately, the diamond’s look is affected by the choice of metal for the setting as well as the shape and the cut of the diamond.

Diamond Color Grade Chart

D: An Exceptional, Most Rare Diamond

E, F: Colorless, Very Rare Diamonds

G, H, I, J: Near Colorless Diamonds of High Value

K, L, M: A touch of brown or yellow tint

N to Z: Diamonds with heavier tints

Artificially Colored Diamonds | Fancies

With the development of technology and the rarity of naturally colored diamonds, it became necessary to artificially add color to diamonds by treating them chemically.  Diamonds which have been artificially colored are called enhanced diamonds.
