Heulandite Crystal cluster
Heulandite Crystal Cluster – This exquisite cluster showcases perfect rhombic monoclinic crystals of Heulandite in a matrix, boasting a beautiful caramel coloration. Heulandite, belonging to the Zeolite group, can manifest in various colors depending on its composition. Typically found alongside stilbite and other zeolites in the amygdaloidal cavities of basaltic volcanic rocks, as well as occasionally in gneiss and hydrothermal veins. It forms at temperatures below about 100°C, indicating shallow diagenesis in sedimentary rocks where it is present. This particular specimen hails from the Deccan Traps of the Sahyadri Mountains in Maharashtra, Poona – India. Mounted in a handmade dark brass base.
