Description |
Zacatecas is a classical locality for fine Jamesonite specimens, including this one. It features matte black, thick and elongated crystals up to 3 cm in length. In addition, there are well placed bright, lustrous Pyrite crystals. In recent years there has been a paucity of this great sulfosalt mineral. This locality still ranks among the best for species, because of the thickness and sturdiness of the crystals which normally occur simply as a jumble of acicular needles from other places. Very rare in this quality! |
