Diamond Basics

Diamonds are known to be a girl's best friend, but on the flip side I can see how it can also be a guy's worst nightmare. So we are going to break the different components of a diamond down and start with the basics.

I'm sure somewhere or another you've heard of the 4 C's. But just in case you've been living under a rock for the past few years or even a decade, here they are:

1. Cut
2. Carat
3. Color
4. Clarity


Cut, in this instance, refers to the shape of a diamond.


Many people get confused with carat and size. The carat actually refers to the weight of the diamond.
1 carat is divided into 100 points like a dollar is made of 100 pennies. That is why sometimes you will hear jewelers refer to a half-carat, 0.50ct, as a 50 pointer. 


It's funny to think that diamond color grading is based of how colorless a diamond is. The color scale ranges from D to Z, D being the highest grade and Z being the lowest grade. It's easy to remember because the word "diamond" start with "D" and the rest just goes down the alphabet. 


Clarity is graded by the visibility of the inclusions (inside the diamond) and blemishes (outside the diamond) or identifying characteristics a diamond has.  You can think of this characteristics like fingerprints or snowflakes. No two diamond have the same exact inclusions. Diamonds are grade using 10x magnification.

That's just a brief overview of the 4C's and the first steps to understanding diamonds.

According to National Jeweler
July 09, 2008

London—Sightholders collecting their boxes of Diamond Trading Co. (DTC) rough earlier this month paid as much as 15 percent more for larger goods, according to a release from the DTC.

According to the DTC, prices for rough goods increased by an average of more than 5 percent at its July 7-11 sight, the sixth sight of the year.

Prices for rough that produce higher-quality polished diamonds of more than one carat increased as much as 15 percent.

"In arriving at this pricing approach, we have been closely monitoring the polished-diamond market and, using data from multiple sources, have adjusted prices while taking a long-term and sustainable approach to our pricing," the DTC stated in a notice sent to sightholders.

The DTC has committed to announcing price increases to its sightholders three times a year: before the company's annual results are released and at the sights preceding the industry's two major trade shows, JCK Las Vegas and the Hong Kong Jewellery and Watch Fair.

The transparency regarding price increases developed from feedback received at the Sightholder Consultative Committee, held in April. There, sightholders expressed a "keen" desire to know more about why and when prices will be going up or down, according to the DTC.

The DTC states that it will be providing its next cumulative price update at the August sight, scheduled for the week of Aug. 18."
