Mineral dealers are individuals or businesses that buy, sell, and trade various types of minerals and gemstones. They often source their products from mines, rock hounds, or other collectors. These dealers may operate online, at mineral shows, or in physical stores, providing a wide range of items for collectors, hobbyists, and researchers. Many mineral dealers specialize in specific types of minerals, such as quartz, amethyst, or calcite. They may also offer services like appraisals and educational resources about mineral identification and collection. This helps enthusiasts learn more about their specimens and the geology behind them.
