About US Mineral Exchange. The US Mineral Exchange is an online platform designed specifically for mineral owners. Our education center helps mineral owners understand the industry, what factors affect the value of their minerals, and how the process of selling or leasing their minerals works.
It is time â¦ the countdown to Tucson, the largest gathering of Gems and Minerals shows in the world! (January 30th through February 5th, 2018). Come visit our ICA Pavilion, along with many others of our ICA membership, in the Gem & Jewelry Exchange (GJX) tent. The GJX is located directly across the street from the American Gem Trade Association (AGTA) GemFair in the Tucson Convention Center (TCC), (which is where you will find me and my staff in the ICA booth).
