A very small sample of some of the many agates which are found all over the world. Agate is a hard stone, usually within the range of 7-9 on the MOHS scale and is found in all colors of the rainbow.
Often tiny quartz crystals form within the stone and add to the beauty and uniqueness of individual stones. These crystals are called drusy (sometimes misspelled as druzy). Lapidaries often cut just the drusy from an agate and jewelers use these drusy cabochons as the main stone or as an accent stone in their jewelry designs.
