The Rio Gemstones team sees thousands, heck, tens of thousands, of gemstones every year. Rarely does a week go by that one of us doesn’t turn to the other and say, “Hey check out this cool inclusion…” Until this week, though, we had never seen (except in books) hematite needle inclusions inside an amethyst.

From the Medieval to the avant-garde to the diamond-studded, the exhibits offer a little creative rejuvenation in the dark days of winter.

Did the stork arrive at your doorstep yet? You know, the mythical bird bringing the bouncing bundle of joy that is the 2013 Gems & Findings/Display & Packaging catalog? Okay, perhaps the latest Rio catalog is not your baby, but it surely is ours. After seven months of production, thousands of man (and woman!) hours, and hundreds of pots of coffee, the 2013 G&F/D&P catalog came into the world (and hot off the press) on June 20, 2012.
