Naica, Mun. de Saucillo, Chihuahua, Mexico Look at the superb sharpness and size of the central crystal on this fine Naica galena! In person, the faces shine like a MIRROR. This is actually one large, compound crystal, but for the sake of clarity, that central part (which we are calling the central crystal) measures about 4.7 cm. This old Naica piece is complete on the front, with clean ... |

Naica, Mun. de Saucillo, Chihuahua, Mexico 10.4 x 9.9 x 5.5 cm. A big, rich specimen of galena from the older mining there, not the recent finds. This is a dense cluster of very sharp crystals with a high metallic luster, both octahedrons and cuboctahedrons. There are a couple of areas of wear, but overall it is in very good shape. The crystals are all around this specimen - the matrix in ... |

Naica, Mun. de Saucillo, Chihuahua, Mexico 2.7 x 2.4 x 1.6 cm. Look at the fabulous luster on this cluster of super-sharp crystals (actually a compound crystal) of galena from Naica! Naica is known for its fluorites, often in association with sphalerite and galena. But you occasionally get these fine standalone galenas as well. |

Naica, Mun. de Saucillo, Chihuahua, Mexico 10.8 x 9.6 x 4.9 cm. A large and VERY impressive Naica galena, not from the recent finds of galena, fluorite and sphalerite, but from old mining at this classic locality. There are dozens of wonderfully-formed, shiny crystals here, sharp as can be - attractively isolated by a sparing amount of matrix. There are all sorts of variations on the basic ... |
