Clustered on a matrix of spiky, white, chalcedony are a group of lustrous, translucent, light salmon stilbite crystals, to 7.0 cm across. Adjoining is a cluster of mint green, brilliantly glassy and lustrous, translucent, fluorapophyllite crystals to 3.5 cm across. Beautiful contrast, pristine specimen, and a good size at a relatively cheap price (in my opinion...I think its less than I paid). OK, yes, each of these species is common, technically speaking. However, superior combination pieces with such balance, in this quality, are NOT common at all.
