Large, perfect gem clear crystals of Albite with fine textbook form. Ex Rock Currier collection (label # 3856) this shows well the quality of esthetics that Rock was well known for. It is surprising how few collections or even Pegmatite suites we see have a good example of this common Feldspar. These are almost never so esthetic as seen here, this is a striking piece. Albite/ Cleavlandite is a common mineral, but crystals of this size and perfection are just very rare. These crystals are formed as thin hexagonal plates with beveled edges and transverse striations. The whole group is stacked as an epitaxial cluster and shows brilliant glasslike luster. A killer Feldspar, some edges have a dusting of small rosettes of Muscovite that add a nice contrast. Better in person, the individual crystals exceed 5 CM diameter.
