A Consumer Guide to Diamonds
Today the 3P’s are as important as the 4C’s.


No wonder the jewelry industry—in close cooperation with human rights groups, NGOs, the United Nations, and the U.S. Congress—has spent most of this decade bringing the problem of “conflict diamonds” under control. Jewelers like Stern no longer have to call their suppliers for geopolitical assurances about their diamonds. They are receiving such assurances on invoices and even on diamond certificates.

Many diamonds today also have been tested with advanced technology to make sure that they are natural and have completely natural color.

Today, for the first time in history, manufacture of high-grade man-made gem diamonds is a global reality. These synthetics are clones of nature grown in labs and detection of them requires expensive technology. What’s more, natural diamonds are being subjected to very sophisticated color and clarity improvements that challenge their identity as natural wonders. Such doctoring takes very advanced technological sleuthing to uncover. Few labs have the equipment to ferret manufactured from mined diamonds. Proof of natural origin and unenhanced color now requires a report from a major laboratory.

The need for technology doesn’t end with gem identification. In the past decade, cutting has become the most important attribute of diamond value because it has the greatest bearing on beauty. Beauty is now defined as a trinity of light-performance factors: brilliance, fire, and sparkle.

And judgment of performance is no longer as subjective as it used to be. Various instruments measure diamond proportions to predict light behavior while others analyze and grade actual light output. In addition, special viewers map the diamond’s light handling capability. Top jewelers are using these instruments to demonstrate the beauty and quality of craftsmanship of the diamonds they sell. And savvy consumers are using these tools to choose a diamond that is high in performance.

Years before it first proclaimed a “Diamond is Forever” in 1948, De Beers was promoting the 4C’s—color, clarity, cut, and carat weight—as the basic criteria of diamond beauty and value. Indeed, for 60 years, the 4C’s were the underpinning of diamond education and marketing.
