Description
This magnificent large cabinet specimen of colourless to smoky grey crystallised Dolomite is from the Azc'rate quarry (Azkarate quarry) by the village of Eugui in Ester'bar, Navarre in northern Spain; only about 7 km from the French border. Sharp, rhombic Dolomite crystals up to 6 cm on edge form a piled-up jumble of crystals on top of a large plate of mixed Calcite-Dolomite matrix. In front of these are countless Dolomite rhombs of between 0.4 and 1.0 cm, with one group to around 1.8 cm on edge. Many of the larger crystals display phantom edges, zoned colourless and in shades of light and dark smoky grey. All the Dolomite crystals are translucent, but the larger ones do become transparent in many areas, sometimes becoming gemmy. Azc'rate quarry remains in operation and extracts Magnesite from the dolomitic shales. This is a museum quality specimen from a locality which produces some of the best Dolomite crystals in the world.
