Campo del Cielo Meteorite Necklace
Fell 6000-5000 years B.P.Sold for (Inc. bp): £98
A nickel-iron meteorite (IAB) with a suspension loop and cord for wearing. 6.68 grams, Meteorite: 22 mm
From a Lincolnshire, UK, collection.
A crater field of roughly 26 craters was found in the vicinity of this crater, which is estimated to date to 4-5 thousand years BP. The age of the meteorite itself is thought to be c.4.5 billion years, formed as part of the development of this solar system. The largest two fragments, the 30.8-ton Gancedo and 28.8-ton El Chaco, are among the heaviest meteorite masses ever recovered on Earth. In 1576, the governor of a province in Northern Argentina commissioned the military to search for a large mass of iron, which it was believed the local people claimed had fallen from the sky and which they used for their weapon production. The expedition discovered a large mass of metal, which was assumed to be an iron mine, and brought back a few samples, which were described as being of unusual purity. Following the legends, in 1774, Don Bartolomé Francisco de Maguna rediscovered the iron mass. He himself did not believe that the stone had fallen from the sky and assumed that it had formed by a volcanic eruption. However, he sent the samples to the Royal Society of London. In 199,0 it became protected by law. -

Previously from a Hong Kong collection. Ex property of a London, UK, gentleman, 1990s.
A stalagmite, is an upward-growing mound of mineral deposits growing on the floor of a cave due to accumulation of material deposited from ceiling drippings. They are typically formed by the deposition of calcium carbonate and other minerals, which is precipitated from mineralised water solutions. Limestone is the chief form of calcium carbonate rock which is dissolved by water that contains carbon dioxide, forming a calcium bicarbonate solution in underground caverns.
