This small hand specimen consists of 2 Ludlamite "clusters" that rest on opposite sides of a brown base rock. These clusters are so heavily intergrown that isolating individual crystals is nearly impossible. The clusters do not exceed 0.4" along any axis, have a moderately pale green coloration and a greasy luster and are translucent. Actually they closely resemble the mineral anapaite, which is closely related, chemically. The brown base rock is also host to a crust and several botryoidal formations of a sulfide mineral that I cannot identify- it likely has iron in it, however, due to its association to the Ludlamite and the general red-brown color of the base rock.
