Size: 95 x 55 x 45 mm. 352 grams From Cubuk, Ankara Province, Turkey Botryoidal agate is a type of agate that has a rounded, grape like appearance. It is formed when silica rich water fills cavities in rocks and deposits layers of chalcedony, a microcrystalline variety of quartz. The botryoidal shape is created by the growth of tiny spherical crystals on the surface of the chalcedony.
