NA420 - Barite on Calcite $ 350 Elk Creek, Meade Co., South Dakota miniature - 3.2 x 2.8 x 2 cm - GEM Barite crystal on matrix of yellow Calcite. The main Barite is 2.7cm tall and transparent top to bottom and spectacular. A smaller side crystal has a truncated termination but is undamaged. There is a tiny ding near the termination of the main crystal that is way more noticable under the magnification of the photos than when held in hand. The Barite has great luster, a very showy specimen...
