I have made over 50 trips to Mexico to buy minerals specimens, especially silver minerals like this one. It is <u>very hard</u> to get matrix pieces or association pieces like this one. Somehow this piece reminds me of a tank turret with quartz guns or maybe an alien robot with quartz arms. The pyrargyrite is very bright and shiny even though I brought this piece back from Mexico about 20 years ago. This piece measures 2.1 x 2.7 (including the arms) x 1.9 cm. It weighs about 14.7 grams.
