A 1.5cm crystal of Chrome Tourmaline in Calcite - this is uncommon for this major find as most were single crystals off matrix. Glassy and gemmy crystal with vivid green color, however termination is contacted where another (former) crystal intergrew with it. Chrome Tourmaline is a chromium and vanadium rich Dravite. From a spectacular pocket opened in 2016. Only a small number found were matrix pieces.
