“This specimen hosts a large, pristine crystal of heulandite in association with several smaller heulandite crystals prominently perched atop a small portion of matrix. The heulandite crystal has razor sharp faces and brilliantly glassy luster. The specimen retains an old affixed label (erroneous "stilbite") as well as a label from the A.E. Seaman Mineral Museum with L.L. Hubbard Collection (1849-1933) notation.”
