WOW! Sharp and brilliant atacamite crystals on quartz and chrysocolla matrix! The atacamites are grown in wonderful groups and reach up to 19 mm in length. The plate of matrix is richly covered, and the quartz sets a pleasing contrast. Some of the crystals in the lower part are not terminated, but the majority is well formed and in perfect condition. One of the very best atacamite specimens ever found at the Lily mine!
