In the center of this matrix specimen is a large, rather equant, rhomb of glassy and translucent, calcite, measuring 1.9 cm across.It has been mostly included by fibrous aurichalcite, exhibiting a spectacular, teal blue color. The top left termination is gemmier due to a smaller amount of aurichacite and thus more transparency to the calcite. This is a stark and dramatic miniature! When closely examining the calcite, it is possible to see the fibrous aurichalcite crystals preserved inside, thus showing that this is intergrowth, as much or more so than simple inclusions. Some crystals of calcite may be more aurichalcite than calcite now! The color is, truly, mesmerizing! Because they are also lustrous, this is hard to photograph and I assure you the color and luster both are better in person because we had the camera compromise to try to get each in some degree.
