Remarks:A pallasite is a class of stony-iron meteorite

Pallasites are a rare type of meteorite. Only 61 are known to date, including 10 from Antarctica, with four being observed falls.

Meteorite that contain fragments of gemmy olivine and/or peridot crystal are called "pallasite", or "stony-iron meteorite." When sliced into thin layers, these olivine and peridot fragments are transparent next to the opaque nickel-iron matrix they are contained in.

Sericho: a new main group Pallasite with two types of chromite. J.S. Boesenberg1. Sericho is a new Main Group (MG) pallasite discovered in Kenya in 2017.
History: In 2016, two brothers were searching for their camels and came across several large, dense stones west of the village of Habaswein and south of Sericho, Kenya. There are no rocks in this area, so they decided they were meteorites. They spent several weeks collecting them with engine hoists and moving them to their homes in Habaswein. Though recognized as meteorites in 2016, the masses had been known to camel-herders for decades. One village elder said that as a child, he and his brothers would play on top of the stones. In early January 2017, Michael Farmer received an email showing a photo of "giant pallasite" weighing 107 kg. He traveled to Nairbobi and purchased this stone. Two weeks later he returned to Kenya with Moritz Karl and traveled to Habaswein. Here they were shown more than one ton of specimens stacked in the courtyards of two house compounds. To date, more than 2800 kg has been found.2

Classification of Meteorites
1. Iron Meteorites
  Iron meteorites are composed of iron and nickel and are extremely dense. They are pieces of the cores of asteroids. Early in Solar System history, asteroids melted and the dense iron-nickel metal sank to the center to form a core - much like the Earth has a core.
One of the most distinguishing features of meteorites is the presence of the Widmanstatten pattern - the distinctive series of bands in geometric patterns. This pattern is created by the intergrowth of two different iron-nickel minerals formed during very slow cooling (a few degrees every million years) in the core of the asteroid. The presence of nickel is a universal feature of iron meteorites.
Iron meteorites are subdivided into classes both by chemical composition and structure. Structural classes are determined by studying their 2 component iron-nickel alloys: Kamacite and Taenite.
 
  1.1 Kamacite  
  Kamacite is an alloy of iron and nickel, the proportion iron:nickel is beteween 90:10 to 95:5; small quantities of other elements, such as cobalt or carbon may also be present.
It is a major constituent of iron meteorites (octahedrite and hexahedrite types).
In the octahedrites it is found in bands interleaving with taenite forming Widmanstatten patterns.
In hexahedrites, fine parallel lines called Neumann lines are often seen, which are evidence for structural deformation of adjacent kamacite plates due to shock from impacts.
Hardness: around 4

Gibeon Meteorites
hot sell
The Giben Meteorite is a fine octahedrite iron meteorite which flamed into our atmosphere as a visible star-like streak an estimated 30,000 years ago, landing in what is present day Namibia. Prior to this, the Gibeon meteorite traveled through space for over 4 billion years before it was finally trapped by the Earth's gravitational field and pulled to earth as a fire ball.

Agoudal Iron Meteorite

Also Known As: Imilchil. In 2000 two small pieces of "iron" were collected in the Agoudal area, High Atlas Mountains, Morocco. Later in September 2011, one piece was sold to a dealer who recognized it as an iron meteorite. Since then many more pieces have been collected. Type IIAB iron meteorites are also called hexahedrites. Hexahedrites are low nickel iron meteorites.

Taenite (Fe,Ni) is a mineral found naturally on Earth mostly in iron meteorites. It is an alloy of iron and nickel, with nickel proportions of 20% up to 65%. Taenite is a major constituent of iron meteorites.
In octahedrites it is found in bands interleaving with kamacite forming Widmanstatten patterns

2. Stony Meteorites
 
  More than 95% of meteorites observed to fall to Earth are stony.
They can be divided into chondrites and achondrites.
Both types are composed mostly of silicate minerals, but the great majority also contain metallic iron in small-scattered grains.
 
  2.1 Chondrites
  Chondrites are named for their most prominent feature - millimeter-sized spherical bodies called chondrules. These chondrules (from the Greek for small sphere) formed 4.5 billion years ago in the Solar Nebula - the cloud of gas and dust from which the Sun, planets, asteroids, and comets formed.

The descent of the meteor, visible as a brilliant superbolide in the morning sky, caused a series of shock waves that shattered windows, damaged approximately 7,200 buildings and left 1,500 people injured. The resulting fragments were scattered over a wide area.

  2.2 Achondrites
  Less common, comprising only a few percent of all meteorites, are achondrites. These are also stony meteorites composed primarily of silicates, but these meteorites have experienced familiar geologic processes of melting and differentiation - although these happened long ago. Most achondrites formed on asteroids during the birth of the Solar System, but a small number formed on Mars and the Moon.

3. Stony-iron meteorites  
  Stony-iron meteorites, contain about equal proportions of metal and silicate material, and are rare (less than 2% of all known meteorites). Stony-iron meteorites form in places where metal and silicate are mixed. They are divided into two groups: the pallasites and the mesosiderites  
  3.1 Pallasites
  One type of stony-iron are pallasites - rocks composed of a network of iron-nickel metal surrounding a greenish, silicate mineral called olivine. Pallasites probably form when the olivine-rich mantle of an asteroid mixes with the metallic core.

Functions:
1. Stimulates the loving energies of the heart chakra, along with the visionary capacities of the third eye.
2. Pallasite opens the emotional gateway of the heart along with the inner eye of wonder and expanded awareness, for the purpose of allowing one to experience the link between oneself and the cosmos.
3. It can calm the fear of flying and can also assist those who suffer from agoraphobia.
4. Pallasite can also assist one in manifesting prosperity and abundance in one's material life.
5. For opening the heart more fully, one can combine Pallasite with Dioptase, Morganite, Emerald and/or Kunzite.
6. Hematite, Black Tourmaline, and Smoky Quartz are all excellent choices if one feels that a grounding influence is needed.
   
General care:
 
1. Meteorite can be scratched easily, so wear with caution.
2. Do not soak in water.
3. Do not soak in jewellery cleaner.
4 Avoid contact with household cleaners.
5. Avoid using ultrasonic and steam cleaners.
6. Cleaning: Clean using lukewarm plain water and soft brush, then dry using a soft cloth. (Do remember to dry it cause meteorite might oxidize easily!)
