Making the Right Decisions in “Rough” Diamond Times
27 july 2015
(www.ehudlaniado.com) - At De-Beers' last Sight, more than half of the goods were refused or deferred. According to several Sightholders, as much as 60-90% of the offered rough was turned down by many. A few did not buy any of the goods, turning down their entire allocation. The past sentiment of buying out of loyalty and an understanding that they will be compensated down the line is gone. Now Sightholders say they'll buy rough diamonds only if they can make a profit. This sentiment, while new, is already impacting miners. According to production and sales results published in the past few days, miners are starting to feel the impact of refusals.

Diamonds could help bring proteins into focus
22 july 2015
(R&D) - Proteins are the building blocks of all living things, and they exist in virtually unlimited varieties, most of whose highly complex structures have not yet been determined. But figuring out the arrangement of atoms in these complicated molecules usually requires getting them to form crystals large enough to be observed in detail—and for many proteins, that is either impossible or dauntingly difficult. Now a new technique being developed by researchers at Massachusetts Institute of Technology (MIT) and elsewhere shows great promise for producing highly detailed images of individual proteins. The technique makes use of microscopic defects within the crystal structure of diamond.
