The natural pattern on the current bottle resembles a tree, standing above its reflection in a pond or still pool. This type of agate, often called mocha stone, is noted for the complete images in the stone which can resemble a fern or tree. These dark russet designs are caused by manganese or iron oxide deposits in the stone. For a discussion of mocha stone snuff bottles and other agate bottles, see H. Moss in Chinese Snuff Bottles of the Silica or Quartz Group, London, 1971, p. 15, nos. 25 and 26.
