You are bidding on an excellent thumbnail of this rare material with large green clusters of borcarite blades hosting numerous grey, vitreous groups of cahnite tetrahedra. This material is best of for both species, and the exact location is still uncertain. Some say the material is from the nearby Shijiangshan Mine. Either way, this is rare material and very unusual!
