There is something really weird about the agates from Trent, Oregon. The location may be the only one in the world where the agates are found with stibnite, meta-stibnite, realgar(altered to orpiment when exposed to light) inclusions. They appeared to have been collected in the past and it's not known if they still can be found today.  The agate is a vein type and are colorless, sometimes with yellow tint and banding features. Realgar can be noted by either breaking or cutting the agate clunks, but  they will eventually be altered to orange orpiment once exposed to the light.
