This is just a drusy crust of azurite on goethite matrix, on one level. But it is so pretty, so shockingly and intensely blue. The crystals are sub-millimeter, but there must be thousands of them, and they sparkle like sugar. Although not a significant azurite in standard terms, this is a gorgeous specimen. From the well-known Tucson collection of 40-year collector, Harold Urish.
