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


The upshot: Most jewelers won’t sell you a significant-occasion diamond today that hasn’t been cleared for commerce by a reputable gem lab. Believe it or not, your diamond is subjected to the gemological equivalent of a security clearance before it is graded for color, clarity, or cut. (see image 4)




Keeping Diamonds All-Natural

Diamond defense has long been of paramount importance to the jewelry industry, especially De Beers, the diamond mining and marketing company that controls around 60 percent of the world’s annual supply of gem diamonds. At a time when oil companies let pipelines corrode, De Beers practices a vigilant monitoring of the global diamond pipeline that other corporations should emulate.

It has no choice. Unlike oil, which is a necessity, the diamond is a luxury (although try telling that to a couple who feel diamond rings are a mandatory expression of love and commitment).

Driven by both principle and profit, De Beers has waged a full-time, full-scale campaign to protect the integrity of the diamond. It has even run ads to explain what it means by “product integrity” and to pledge itself to sales of diamonds that are 100 percent natural.

The trouble is, some of the industry has a slightly less hard-nosed view of the word “natural.” De Beers wants you to buy treatment-free diamonds.

Not everyone agrees. Some retailers, intent on offering handsome but affordable diamonds, tolerate some high-tech tampering to conceal small but visible flaws or tiny, yet blatant fissures in stones. They feel it helps them offer consumers affordable good-looking stones.

For example, many diamonds lend themselves to laser surgery to remove unsightly black spots. During crystallization billions of years ago, bits of other minerals got trapped inside stones. These particles and flecks can be dissolved or camouflaged by drilling microscopic cavities to their sites and injecting acid.
