Dark blue colored Benitoite crystals which have been acid etched from massive, white colored Natrolite, some of which is still intact. The Benitoite crystals fluoresce a vivid blue under SW UV. There are a few, very small, orange colored Joaquinite-(Ce) crystals scattered across the surface. The location is also the type location for Joaquinite-(Ce). There is also one small Neptunite crystal and some unidentified, black colored, fibrous material present.

Condition: Fairly Good

Flaws: Two of the crystals have chipped areas missing. This includes the largest crystal which has much of one face missing - but the termination is still intact. Many of the other crystals have internal cleaves, but all are terminated.
