A classic, old-time and superb combination specimen composed of huge Siderite rhombs perched on gemmy Quartz. The iron mines of the famous French locality of Allevard, Rhone-Alpes date all the way back to the 1500's. The brownish, olive-green Siderite rhombs have partially stepped faces and the larger crystals are over 3 cm on edge. They rest on water-clear, glassy Quartz crystals that range up to 3.5 cm. There is some edge wear on the rhombs, but it affects the excellent aesthetics very little.
