Monte Azul deposit, Sijes, Salta, Argentina 6.3 x 6.0 x 5.5 cm. A starkly geometric, sharp cluster of three larger crystals (to 5 cm) on matrix, presenting sharp faces, gemmy interiors, and excellent lustre on all sides, 360 degrees. There is some included matrix, which because of the stunning clarity of the crystals shows through here in the photos much more strongly than in person, ... |

Inyoite : Ca(H4B3O7)(OH) · 4H2O, Meyerhofferite : Ca2(H3B3O7)2 · 4H2O | |

Monte Azul deposit, Sijes, Salta, Argentina 11.3 x 10.4 x 4.8 cm. This is my personal favorite of the lot, with sharp and VERY GEMMY, lustrous crystals to 4.5 cm perched atop matrix. The piece just sparkles with minute crystals all over the place. Very minor meyerhofferite threads are present, but only within the crystal cores and not on the outside of the crystals as with other pieces ... |

Monte Azul deposit, Sijes, Salta, Argentina 4.7 x 4.7 x 2.7 cm. A gorgeous, sharp miniature with top lustre and extremely good form, with the 4 x 2.5 x 2.75 cm crystal perched on a natural pedestal of smaller rhombs. There is only a slight contact at the base; otherwise this is complete all around and 360! The Meyerhofferite exists as a network of discrete crystals penetrating the interior, ... |

Monte Azul deposit, Sijes, Salta, Argentina 5.7 x 4.1 x 3.1 cm. A razor-sharp crystal, to 3.5 cm on edge, and extremely impressive in person! One of my favorite miniatures here, this one LOOKS like it has a different crystal form almost, because of the sharp angular nature of its rhombohedral crystals, elongated steeply in one direction. A few gemmy, discrete Meyerhofferite crystals are ... |

Inyoite : Ca(H4B3O7)(OH) · 4H2O | |
|
Monte Azul deposit, Sijes, Salta, Argentina 12.0 x 7.8 x 6.5 cm. Inyoite is a RARE borate. This SUPERB CABINET specimen features HUGE, very glassy and zoned, pseudorhombic crystals that have preferential overgrowth on some crystal faces. The largest crystal is 4.0 cm! This magnificent piece comes from a recent, but small find in arid, high altitude valleys of Argentina. |

Monte Azul deposit, Sijes, Salta, Argentina 6.4 x 4.5 x 3.8 cm. A SUPER SHARP crystal, 3.7 cm long on edge, with extraordinary gemminess and glassy lustre...this is perhaps the best single crystal in this quality in my lot, gram for gram. It is hard to judge from photos due to the clarity and lustre on some of these, but that is my opinion. It is not altered to Meyerhofferite but DOES have ... |

Monte Azul deposit, Sijes, Salta, Argentina 9.6 x 8.7 x 4.5 cm. A razor-sharp 9 x 8 x 3 cm crystal here is one of the largest of the lot and of the find, and it is partially invested with the Meyerhofferite I like because the growths inside create such a stark contrast to the enclosing clear inyoite crystal itself. As well, freestanding meyerhofferite (or perhaps ulexite?) crystals on one ... |

Monte Azul deposit, Sijes, Salta, Argentina 8.5 x 6.9 x 3.7 cm. SHARP crystals to 4.5 cm, partially included by and altering to Meyerhofferite on their edges for a unique visual contrast to the cores, dominate either end of this beautiful matrix specimen. In person it is much less brown and more white and clear...but photos simply do not do these justice: these crystals are so clear, that ... |
