A single, large Phlogopite "book" is partly embedded in the calcite host of this specimen. This book has dimensions of 4.3 x 2.1 x 0.7" (10.8 x 5.4 x 1.9 cm) and is in excellent condition, showing no appreciable damage. Its monoclinic, pseudo-hexagonal form is rather warped but still relatively good, and its black color with brown highlights, pearly luster and flaky habit are standard for the specie. The calcite base also contains 3 partial and 2 complete apatite crystals that are pale green in color, transparent, and quite clear.
