Knowledge DiamondThe Diamond Is An Emblem Of Courage And Invincibility. It Symbolizes Eternal Love, Purity And Faith.



Beautiful, rare and cherished. Every diamond is unique and is a miracle of time, place and change. Each has specific qualities that establish its value. Until the middle of the 20th century, there was no agreed upon standard by which diamonds could be judged. GIA created the first, and now globally accepted standard for describing diamonds: Carat, Cut, Color and Clarity. Today, the 4 Cs of Diamond Quality is the universal method for assesing the quality of any diamond, anywhere in the world. The creation of the Diamond 4 Cs meant two very important things: diamond quality could be communicated in a universal language, and dimaond customers could now know exactly what they were about to purchase.

The term carat is often misunderstood. It refers to a diamond’s weight, not its size. Another misconception is that a larger carat weight is alwys better than a smaller carat weight. While it is true that a large stone can be a status symbol, carat weight is not related to sparkle. Beautiful sparkle is the result of a well crafted cut. In fact, a high carat weight diamond with a poor cut may look smaller than a diamond with a smaller carat weight and a very good cut. Diamonds with higher carat weight are cut from larger rough crystals that are harder to source than small crystals. The relationship between carat weight and price depends on the rarity or availability of a rough crystal. Carat price is also a function of finding rough crystals with desirable color, and internal and exteral characteristcs that will positively influence clarity when the diamond is cut.


Diamonds are renownded for their ability to transmit light and sparkle so intensely. We often think of a diamonds’s cut as shape; round, heart, oval, marquise, pear, but what diamond cut actually does mean how well a diamond’s facets interact with light. Precise artistry and workmanship are required to fashion a stone so its porportions, symmetry and polish deliver the magnificent return of light only possible in a diamond. Achieving the best cut for a diamond refelcets in the stone’s final beauty and value.


Understanding what diamond color means helps in choosing the right diamond. Interestingly, the diamond color evaluation of most gemsone quality diamonds is based on the abscence of color. A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. They are graded from D to Z and the diamond color grading system measures the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions to master stones off established color value. Many of these diamond color distinctions are so subtle that they are invisible to the untrained eye; however, these distinctions make a very big difference in diamond quality and price.


Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth. This process can result in a variety of internal characteristics called “inclusions” and external characteristics called “blemishes”. Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone. They are graded on a scale raging from Flawless, which is pure, to Included, where inclusions are visible to the naked eye. If you are trying to determine what is the best clarity for a diamond, remember that rarely is a dimaond perfectly pure. But the closer it comes to purity, the better its clairty.
