MUSEUM QUALITY METEORITE, HIGHEST QUALITY!!!
Hello up for sale is a new find, with beautiful shape and exceptional features. This gorgeous oriented individual weighs 654.50 grams, it has exceptional fluted regmaglypts and nice fresh fusion crust! This is a fresh and beautiful individual found in Algeria 2023, its unclassified and unstudied. This one comes with a COA card, thanks for your interest.
Regmaglypts are shallow depressions or dimples that form on the surface of some meteorites as they pass through Earth’s atmosphere. They are probably formed by small vortices of hot gas carrying small droplets of molten meteorite that locally erode the surface.
When a meteorite enters the Earth\'s
atmosphere, friction raises the surface of the meteorite above its metling temperature.
As the meteorite descends, it slows down, frictional heating
decreases, and the melt quenches to form a fusion coating, a thin layer of dark
glass. The fusion coating may be black or brown, dull or shiny on a recently
fallen meteorite. After the meteorite has been on the Earth\'s surface for a while,
the fusion coating may rust, giving the outside of the meteorite a reddish-brown
coloring, or the fusion coating may erode off partially or completely. The fusion
coating is a thin, discrete layer surrounding an interior that looks quite different
from the fusion coating. Many Earth rocks can develop a weathing rind (from
chemical weathering) on their exteriors that is similar in appearance to a fusion
coating. However, there is rarely a sharp boundary between a weathering rind
and the interior of the rock. In addition, tiny shrinkage cracks (too small to be
visible in the images below) are fairly diagnostic for fusion crusts and are
generally absent for weathering rinds. The surfaces of many meteorites develop
shallow pits during entry into the Earth\'s atmosphere. These pits, known as
regmaglypts, resemble thumb prints, and are usually better developed on
iron meteorites than on stony meteorites

Origins of Meteorites
Not all meteorites are the same age. The oldest we have recorded clock in at 4.56 billion years old, especially those that come from asteroids. Meteorites from the moon tend to range from 2.9-4.5 billion years old, while those from Mars vary from 200 million to 4.5 billion years old. (8)
