NM91AM9: Very individualized Stephanite crystals, relatively complex and with very well defined faces and edges. Lustrous, and on a matrix with translucent white Quartz crystals that give a nice contrast to the piece. An excellent and rare Mexican classic that comes from the Ignacio Gaspar Sintes collection (number PIR-11), the label of which we will send to the buyer, as well as a copy of the analysis carried out. This specimen previously resided at the Arizona Desert Museum, and in Gregory, Bottley & Lloyd, and in two other private, unidentified collections.
