First InStore Show Draws Rave Reviews
April's Chicago InStore show drew around 400 exhibitors and 2,000 buyers. While this optimism didn’t translate into strong sales, it translated into the kind of strong enthusiasm among vendors and visitors that hopes to ensure a second edition of this event. (May 2009)

Gem Hajj in Quartzsite
Every January, rock and rough dealers from all over America and Mexico gather for a desert sale/swap at Quartzsite 120 miles west of Phoenix just near the California border.

With exhibitor attendance down, and far fewer quantity buyers from Asia, Quartzsite is telegraphing trouble ahead for the colored stone industry’s main event.
