Iris agate is a finely-banded, translucent variety of chalcedony that breaks up transmitted light into spectral colors. The word "iris" means "rainbow" or "to make iridescent" and is derived from the name of the Greek goddess of the rainbow. Watch rainbow colors move across this magnificent slice of iris agate!

Condor agate Iris display. A beautiful and strong example of an Irish band in Agate. At the correct angle, you will get a rainbow effect in the bands that show the iris effect. This happens in various agreements around the world. It is a pretty rare display in most agates. #agate #differentseasonsjewelry #gemology #artist #geology #gemstone #rainbow #gem #crystal | Mark S.
