“7.5 x 6.0 x 5.8 cm. Minerals specimens from this long closed Trap Rock quarry, operated 1905-1922, are rare. This rich specimen hosts 3 extremely rare species from the quarry. Most of the mounded piece is a dense radiating spray of glassy natrolite blades. One side hosts a few light mint-green datolites and another side hosts a 2.5 cm cluster of glassy calcite rhombs. Not great to look at, but this remains a rare and significant combination piece from this old locale. Ex. A.M. Hageman Collection. ”
