An individual agate forms by filling a cavity in a "host" rock. As a result, agate often is found as a round nodule, with concentric bands. In ancient times it was said to quench thirst and guard against fever, and agate bowls were very popular in historical Europe. Shells are mineral structures formed by aquatic creatures and land mollusks. Lustrous shells including mother-of-pearl have been carved into cameos and buttons since antiquity. The beauty and variety of shells make them a sought-after decorative material. Gem quality druzy is created when a layer of tiny quartz crystals forms over the top of another stone. Natural druzy crystals can be colored themselves or take their color from the underlying stone. The surface of a druzy is sometimes coated with gold or other substances for a dramatic effect. Titanium druzy has been treated with a thin layer of titanium to give it a beautiful color and iridescent sheen.
