Very dense and colorful specimen with dark blue Shattuckite, teal Chrysocolla, grey Cerussite, Quartz and other copper and lead minerals. The details are fantastic and using magnification is suggested to see all kinds of crystals in various forms. The Shattuckite is spread to various areas and is in sphere form as well as acicular crystal form, the Cerussite  is what I think may make up the bulk of this specimen with massive inter grown crystals and many well formed crystals seen in vugs. There are some micro yellow Wulfenite crystals that you will need to hunt for with strong magnification as they are micro sized, some well formed blue crystals with a partial coating of light blue Chrysocolla (not identified) etc, a lot of time can be spent on this specimen exploring!
