Recycled Diamonds, Is the Party Over?
04 april 2014
(IDEX Online) - Depending on where you are in the diamond value chain, recycled diamonds are either a great way to make money, or a pain to earnings and margins. Until a few years ago, recycled diamonds, (i.e. previously owned by consumers), were such a small part of diamonds in a store that they were negligible in terms of the industry’s economy. However, according to estimates published by Chaim Even Zohar in the past few years, as much as a billion dollars worth of diamonds are flowing back into the system from consumers.
Colored diamonds are a superconductor's best friend

GIA: Too Big to Fail: Economic Impact Is Concentration Risk
02 april 2014
(IDEX Online) - Let’s get straight to the bottom line: at any given moment, the Gemological Institute of America (GIA) and other grading labs will have some $1.5 billion worth of diamonds in their possession that are not readily available for business. If annual polished consumption is around $22 billion (at polished wholesale prices), this means that, at any given time, some 7-8 percent of annual sales and the equivalent of some 20 workingdays of the global polished-diamond working stocks are withdrawn from the business cycle.

What’s Your Type?
31 march 2014
(Rapaport Magazine) - Like a pretty girl who steals the spotlight from her friends, type IIa diamonds seem to have stolen the headlines of the diamond business. Ask anyone in the industry about diamonds and you’re more likely to get a discussion of the 4Cs than the gemology of diamond types. As the science that identifies and classifies gemological differences among diamond types becomes more sophisticated, more technical characteristics are being used to describe diamond types and refine those descriptions. That, in turn, helps drive the demand and, ultimately, the price for diamonds that meet buyer preferences.
