An Ocos Agate Geode are geodes that have been cut open then polished on the edges. They have not been dyed, as collectors desire their natural color. They have very interesting natural designs on the edges and on some of the crystals inside. Ocos or Ochos are very small geodes that exhibit all the properties of larger agate geodes. The name Ocos comes from the region of Brazil along the Orinoco River where these small geodes are easily found. While not true Ocos Geodes, small 'Ochos' type geodes can also be found in many places, especially in the United States. Some people believe that Ocos came from the Portuguese word for "hollow", and thus any small geode carries the name Ocos or Ochos.
Our daughter-in-law, who operates under the name 'Timeless Designs', recently acquired several of the unmounted Ocos Geods and made them into pendants by wire-wrapping the individual sliced Ocos Geode pieces..
This is a sample of a Ocos Geode that she recently wrapped with silver wire. Small geodes that are crystal lined with miniature mineral formations of goethite, calcite, and occasionally amethyst, are the best looking in pendants. They usually range in size from ¾” to 3” in diameter. .
