About two years ago, amongst the prodigious finds of azurite in China at that time, a few specimens turned up of this amazing "electric blue" azurite; maybe one specimen in 200 had this color. The crystals here are actually little bladed rosettes, with the color alternating beautifully between the electric blue and deeper, more navy-blue crystals.
