The Rock Tumbling Hobby Site - Carnelian

James writes - These are all Carnelian agates; there are a few Brazilian agates mixed in as well. They are from mixed locations. Some of the lighter colored one's actually came from the Rock Shed advertised as "Brazilian agates." I polished these stones in 3 lb barrel. They went in 60/90 for about one month, recharging the grit every seven days. Then they went into 120/220 for 7 days, 500 for 5 days, 1000 Alumina for 5 days and Titanium oxide polish for 6 days.
