"This is what my father taught me to find," said Sean Dunn, President of J.R. Dunn Jewelers. "Not the stone with the best certificate. The stone that stops you."

Diamond Acquisition

The 3.02 carat Old Mine Brilliant diamond (GIA Report No. 5232695813) with a U-V color grade, VS2 clarity, and Excellent ratings for both polish and symmetry was acquired during the Miami Antique Show by Mia Chalik, J.R. Dunn's Graduate Gemologist and diamond buyer. "I look at the material and the make," said Chalik. "Almost any color in a diamond can be beautiful if the cut is right and it's crisp." The 3.02 carat Old Mine Brilliant met that standard on both counts.

The Old Mine cut dominated diamond production in the 1800s. Stones of this era were ground by hand, without the precision tools available to contemporary cutters. GIA Excellent ratings for polish and symmetry on such stones are, according to the company, exceptionally rare.

The diamond is planned to be set in an original design by Robert Pelliccia, the company's award-winning in-house designer, who has been with J.R. Dunn Jewelers for over four decades.
