Outstanding cluster of Prehnite spear-points from the world-famous Jeffrey Mine of Quebec. These beautiful, four-sided Prehnites are gemmy and lustrous, and several are doubly-terminated. It is difficult to say if some of the terminations are cleaved or just naturally flat, but this small variation in form detracts not at all from the excellent aesthetics. This is a classic and uncommon Prehnite crystal form, seemingly distinctive to the Jeffrey Mine.
