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