Diamonds 

 

Quality and value are important when buying an item like a Diamond. To establish a diamond's quality, we examine each of the 4C's - Cut, Color, Clarity, and Carat weight. The combination of the 4 C's determines the value of a diamond. We urge you to take a tour through our 4C's you might learn something new.

  v    CUT - The better cut a diamond has, the more brilliance

  v    COLOR - The less color in a diamond, the more beautiful

  v    CLARITY - The less inclusions in a diamond, the more valuable

  v    CARAT WEIGHT - The larger a diamond, the rarer and more valuable

The Four C's
The price of a diamond varies depending on the four C's: cut, color, clarity and carat weight.

Cut: When a diamond is cut to ideal proportions, light will reflect from one mirror to another mirror like facet to another facet and disperse through the top of the stone, resulting in brilliant display. Diamonds that are cut too shallow or deep will lose light through the sides and bottom of the stone and may have a dark center.

Color: Diamond color is graded on a scale from D to Z. Truly colorless stones are rated D and are extremely rare. Value starts to drop significantly at grades L, M and N, and then increases again at the very end of the spectrum, which includes fancy diamonds that can be yellow, blue, pink or other color.

 


Clarity:
All diamonds have some type of inclusions, or flaws. The difference in the clarity of stones depends on the naked eye or only when magnified 10 times under a microscope or loupe. The location of the flaws also are important. Clarity is graded on a scale with flawless F or internal flawless IF at the top, followed by VVS1 and VVS2 (very very small inclusions), followed by VS1 and VS2 (very small inclusions), followed by SI1 and SI2 (small inclusions) and I1, I2 and I3 which means inclusions are visible to the naked eye. The smaller the number, the fewer the inclusions. Diamonds any lower on the clarity scale are not considered gemstones and are used mainly for industrial purposes.

Carat weight: The carat is a unit of weight derived thousands of years ago from the relatively constant weight of the carob seed. Carats are divided into 100 points. The carat weight is the size of the stone and has no bearing on the color and clarity of a diamond.
