Hidden Gems features some of the most eye-popping color and forms found in nature. Specimens in display are from all over the world, including many from our own region.
San Diego County is one of the best-known gem-producing regions in the world, and visitors will explore some of these local riches—luminous quartz, gleaming topaz, and the signature watermelon-pink tourmalines that have brought fame to San Diego mines.
