Millpillas has produced some amazing crystals over the last 4 or 5 years. Word is that they are finished with the oxidation zone, and are not finding Azurites anymore. I got this piece through a trade. The crystals are sharp, the color is rich and the luster is bright. Also the crystals are pristine without damage, which is so difficult to find from this location. The Malachite jumps in contrast to the blue Azurite.
