Iridescent Gold - Farncomb Hill, Breckenridge, Summit County, Colorado
A stunning example of the naturally iridescent natural golds which came
out in the early 1900s from the famous Breckenridge District of
Colorado, this superb small miniature has crystals of several habits,
accented with incredibly beautiful iridescent patina that one almost
never sees. The reason you do not see the colors on Colorado golds like
this, is most were cleaned with acid. This is probably au naturale,
since the day it came out.
