This small hand specimen consists of scores of tiny Chabazite crystals that rest on a slab of igneous host rock. The crystals do not exceed 0.2" (0.4 cm) along any axis but are in excellent condition, showing almost no human-induced damage. They have the classic rhombohedral form and pearly luster. Their color is a milky-white and they are all at least partly transparent, though most contain veil-like inclusions that give them their color. There is a thin, olive-green colored layer between the Chabazite and the base rock. This layer appears to be made up of small round clusters of tiny needle-like crystals- I cannot identify them, though they make me think of actinolite by their form or olivenite by their color.
