The difference is that Na-Li pegmatites contain minerals such as albite (Na feldspar), lepidolite (Li-rich mica), tourmalines (often gem-grade), beryl varieties (goshenite and morganite
but no aquamarines) and spessartine.
Two especially noteworthy specimens, rare and beautiful with salmon-pink morganite beryl crystals attached to gorgeous pink tourmaline crystals, brought whoops of joy upon being removed from their muddy refuge.
A 6 x 10-inch matrix specimen of vein matter taken from the tan-colored pocket clay revealed the partially hidden shiny facets of a morganite crystal attached to its matrix, with blue tourmaline terminations peeking Out through the clay.
From the same sandy pocket mud that had yielded the morganite and blue-cap pencil crystal on matrix, a similar-sized chunk of mud-covered matrix revealed one more attached morganite, almost identical to the first one, with several mini blue-caps peeping out from the mud.
5-inch group of richly colored blue-caps had formed in a cluster above the matrix just to one side of the morganite crystal that supports a floater quartz crystal.
