A very rich, and surprisingly colorful specimen of covellite from Colorado. Along with Butte in Montana, and perhaps the ancient locality in Sardinia, these are the world's great covellite locales. Good specimens in this size range, though, are few and far between. Colorado covellites have a reputation as being the ugly duckling compared to Butte material but not this one, with its incredible flashy multicolored iridescence. The piece has crystals to over an inch, and very good 3-dimensional relief (also unusual for the locale). Although, as with most covellites from all of these 3 major localities, there is some damage here and there, but this is certainly acceptable in the overall context for the size and quality. I regard this as one of the better Colorado examples I have seen, in this size range.
