The USGS is a science organization that provides impartial information on the health of our ecosystems and environment, the natural hazards that threaten us, the natural resources we rely on, the impacts of climate and land-use change, and the core science systems that help us provide timely, relevant, and useable information.
Our mission with Earth's Treasury is to provide custom fine jewelry and colored gemstones to the public, ethically sourced as close to the mines as possible. We provide a transparent chain of custody from mine to market, and control the entire process of cutting, providing superior precision-cut gemstones with award-winning gem designs. Our primary focus is Montana Sapphires and we are the largest retailer of these rare gems. In addition we provide a full suite of custom jewelry design and manufacturing capabilities using recycled metals and conflict-free diamonds.
