Achondrites are meteorites without chondrules. Achondrite meteorites come from larger asteroids where minerals melted by pressure within the asteroid or where surface collisions resulted in the melting of asteroid material. The giant asteroid Vesta is believed to be the parent body for many achondrites of the Howardite, Eucrite, and Diogenite families of meteorites. Lunar and Martian Meteorites are stones that arrived on Earth from asteroid impacts on the Moon and Mars.
Their lunar and Martian origins have been confirmed through intensive analysis in laboratories using amongst other evidence, the Apollo Moon Rocks, and Martian atmospheric isotopes as references. The origins of Lunar Meteorites and Martian Meteorites are well confirmed today.
New for we created our Moon Dust display boxes for sale. Stony-Iron Meteorites are the family of meteorites represented by the Pallasites and the Mesosiderites. Stony-Iron Meteorites contain approximately half nickel-iron metal. In the case of the Pallasites, the other portion is olivine crystals, the same mineral as peridot the semiprecious gemstone.
Pallasites are beautiful extraterrestrial jewels once sliced to expose their crystals. Mesosiderites contain silicate minerals in addition to the one-half nickel-iron. Mesosiderites often have fascinating textures as a result of the mixing of stone and metallic materials. Tektites are glass objects created by the melting of terrestrial rocks by an asteroid collision with Earth.
This melted and vaporized Earth rocks were thrown and blown high into the atmosphere where the material cooled into aerodynamic shapes as the blobs of plastic glass fell back down. Tektites are not meteorites but have their origin in catastrophic cosmic impacts. Impactites are the altered rocks found at asteroid impact sites on Earth.
Impactites are often glassy and frothy which demonstrates the tremendous heat released by asteroid collisions. Unclassified Meteorites are genuine meteorites that have not been sent to a laboratory. Unclassified stone meteorites will show features like chondrules in the cut slice or windowed surfaces we place on them. If they have fusion crust on the outside or metal grains internally these features will show.
It is from our supply of genuine but unclassified meteorites that we manufacture our meteorite cabochons. We Buy Meteorite Collections. Copyright — The Meteorite Exchange, Inc. My Account.

Sometimes the buyer may have a choice about the type of specimen for the particular meteorite they will purchase.
The Chelyabinsk Russian Meteorite that so dramatically fell over Russia on February 15, is a great example of a meteorite that is perfect for getting in several different forms. At times it is available for sale as slices, impact melt, fragments and whole individuals. Sometimes collectors need just a representative piece to fill a slot in their collection. In this case a small slice or fragment is all that is required.
A good online catalog will usually have the meteorites organized by family and type with a photograph of the specimen you are buying. Our catalog for instance has a large selection of meteorites of all the groups.
Good choices for the beginning collector might be Al Haggounia a EL3 type. It has been on Earth long enough to be referred to as a paleo meteorite. E chondrites are one of the less common chondrite groups. The E stands for enstatite the main mineral found in them.
Another nice choice for one of the first meteorites in any collection is NWA This is a fascinating stone that is made of bits of several different classifications of meteorites which have reformed into a new mass before falling to Earth.
Classified as a type L3. It may be one of the most interesting meteorites to come along in many years. Besides the large group of Chondrites that have the round structures called chondrules are the Achondrites which do not have chondrules.
These have been heated more and have often formed by different processes than the Chondrites. There are many subgroups of Achondrites also. Two very nice ones for any collector to acquire are Tatahouine a diogenite which was a witnessed fall and is a fascinating meteorite. There are only 22 angrites known out of tens of thousands of meteorites that have been classified.
Some collectors purchase only Falls; meteorite events which have been witnessed entering the atmosphere and have pieces found quickly thereafter. Sometimes pieces may continue to be found for years.
Getting pieces of falls is tricky in itself. Usually, no one knows how many stones will be found with a fall. If you buy too early after the event, before the area of the fall has been fully explored you will for sure get a specimen. But, you may pay more than if you waited until the hundreds of additional stones have been collected and the price has fallen. You might also have had a better choice of stones to choose from by waiting.
On the other hand there have been times when just a handful of stones were found and the only ones to obtain pieces were the persons who bought fast and had the budget to pay the high price. Meteorite collecting can get exciting at the time of Falls. Gao-Guenie is a wonderful meteorite which fell in and has continued to be found since.
They are often. Another great meteorite fall was that of the Allende meteorite. It is a member of the Carbonaceous Chondrites which as a group are the most scientifically important meteorites. Carbonaceous Chondrites are some of the most primitive of the stones. They often contain material that came from beyond our solar system and is older than our solar system. Allende is a great meteorite of the CV3 type which will enhance any collection.
It is available as whole and broken individuals and as slices and pieces with polished windows depending on the collectors taste.
Both of these can be found in our catalog. Some meteorites are beautifully shaped and are displayed as natural art. Others are jokingly referred to as space potatoes. These latter ones have little in the way of form and virtually not external appeal at all. These will often be cut into slices and end pieces.
Though they were just blobs from space uncut, they may be wonders of beauty and opportunities for knowledge inside. There is an opportunity for a bargain sometimes by taking the shapeless plain looking meteorite.
One of the nicest meteorites to be classified recently is NWA It had little going for it on the outside, but when we saw it cut we knew it was very special. It is a type LL3 and loaded with chondrules. We have slices of this beautiful meteorite for sale. Type LL3 meteorites are among the rarest of the ordinary Chondrites. Pieces of some types of meteorites can be hard to obtain. An iron meteorite fell on the Sikhote-Alin Mountains, in southeastern Russia, in Though large iron meteorite falls had been witnessed previously and fragments recovered, never before in recorded history had a fall of this magnitude been observed.
