A sliver of natrolite matrix adorns the base of this well formed lustrous, black crystal of neptunite. It is perfect and complete 360 degrees. This is simply an OUTSTANDING thumbnail specimen of competitive quality. It comes from the (Midwest Federation) award-winning case of TN specialist Robert Randall, and was obtained by him from Jaye Smith in 1988.
