Statistics and information on the worldwide supply of, demand for, and material flow of gemstones.

Overview

The terms "gem" and "gemstone" mean any mineral or organic material (e.g., pearl and petrified wood) used for personal adornment, display, or object of art because it possesses beauty, rarity, and durability. Of the 2,700 mineral species, only about 100 possess all these attributes. Silicates compose the largest group of gemstones; oxides and quartz compose the second largest.

We are currently in the process of transitioning our datasets to the USGS ScienceBase platform to improve long-term accessibility, documentation, and version control. As part of that transition, we have temporarily paused public posting of our Mineral Industry Surveys (MIS), so the latest available posted data are from December 2025. We will start publication of the MIS as soon as this process is completed. Users subscribed to the automatic notification will be informed as each MIS becomes available. Thank you for your patience.
