Etched Meteorite Slice

$20,000

Acid etched on both sides, a Seymchan slice beautifully displays the coarse octahedrite texture characteristic of this famous meteorite. An important diagnostic tool used in meteorite identification, the process of acid etching exposes the distinctive geometric patterns known as Widmanstatten patterns which reveal the crystalline structure of the meteorite. These patterns are not seen in any metal originating on Earth. Seymchan was discovered by a geological survey party near the Hekandue River, in the Magadan District of Russia. A very decorative and intriguing piece, olivine crystals are seen at one edge of this complete slice.

Iron, Coarse Octahedrite Gran Chaco, Argentina The Campo del Cielo meteorite is woven into the history of Argentina and the world. In 1576, nearly 4,000 years after Campo del Cielo collided with Earth, native South Americans told Spanish explorers of the heavy metal that fell from the heavens which gave rise to the name of this famous locality, translated as Field of the Sky. Spanish explorers, unaware of their extraterrestrial origin, wrote about the curiously heavy masses and endeavored to extract precious metals from them until 1770. It was not until 1962 that a comprehensive study of the locality was made. Campo del Cielo meteorites are classified as polycrystalline, coarse octahedrites with a significant amount of silicate-graphite-troilite inclusions. The present colossal specimen displays subdued patina and desirable remaglypts (popularly known as thumb prints) which evidence the intense heat and pressure exerted on the mass during its fiery entry into Earth’s atmosphere. The presence of remaglypts over the entire surface of the specimen indicates that it tumbled through the atmosphere, turning at every angle, before its final impact. This is a stupendous specimen which could provide the cornerstone of a serious meteorite collection. Offered on an artistically designed acrylic stand evoking meteoritic texture.
