There are several well formed Benitoite crystals at the end of this specimen. The crystals are semi gemmy. have good luster and are a medium blue color (note: the pictures had to be edited and the blue color toned way down which is why there is some variation in the color; the pictures with the least vivid color are probably the most representative). There are also small red/brown colored Joaquinite-(Ce) present. The gray/blue colored matrix is Crossite. The white is Natrolite.
Flaws: Some of the crystals are incomplete.
