Small Cabinet - 5.5 x 5 x 2.5 cm
Deep blue crystals of Benitoite to 2.1cm on schist matrix with white Natrolite. This specimen has two qualities which most do not have - deep blue color and good luster. The color is as good as it gets and the luster is good. A small shallow nick on the large crystal is the only detraction I could find. Uncommon to find them this good!
