Diamonds are the heart of the jewelry industry. Of critical importance is the continued supply of fine diamonds from the mines into the marketplace. The article on recent research into the age, origin, and emplacement of diamonds featured in this issue reviews new developments that will be useful in the exploration and mining of diamonds for years to come. It coincides with the celebration of GIA's diamond anniversary—60 years of service to the jewelry industry. In fitting tribute, this 89.01 ct D-internally flawless modified shield cut—the Guinea Star—sits above a group of fine rough diamonds that range from 0.74-12.76 ct. The faceted diamond is courtesy of William Goldberg Diamond Corp., New York; the other diamonds are courtesy of Cora Diamond Corp., New York. Photo by Shane McClure. |
