This plate of black neptunite and blue benitoite crystals on white natrolite is one of the nicest I have seen in years for its price and size range. The neptunites reach 3 cm in length and are EXTREMELY sharp and lustrous. The largest benitoite measures 1 cm across with good luster and is tha tmost rare thing, a complete triply-terminated crystal perched smak dab on matrix, staring you in the face. Smallish perhaps, but of great quality and some gemminess as well. In addition, there is a rare, tiny 0.5 mm, brown, joaquinite crystal in the right center of the specimen. If the crystals stood more vertically, this would easily be a multi-kilobuck piece.
