Since its discovery by a teenager in 1859, thousands of specimens of lustrous black tourmaline crystals from Pierrepont, New York, have found their way into both museum and private mineral collections worldwide.
From an historical standpoint: Tourmaline is possibly the "Lyngurium" -green at one end, light colored at the other-that Theophrastus (ca.315 B.C.) described in On Stones, the first known book about minerals.
This book contains classic material dating back to the 1900s and before.
