I did my best but could quite get the Iris in these Montana agate bands to come through in a picture. It’s very gentle, but when you hold these up to the light you can just see the entire rainbow spectrum of light. The way the agate formed diffracts the light through the bands create the rainbow and it is awesome.
These are pretty long but very light, 3 inches. Handcut Montana agate, silver + 14/20 gold fill
