Vist our website to view our Allende meteorites for sale . Every collection should have a representative specimen of Allende. Carbonaceous chondrites are believed to be one of the earliest forms of matter in space. Allende is rich in large chondrules and scattered through the matrix are irregular masses called Calcium Aluminum Inclusions or CAIs. Allende also contains microscopic diamonds that are among the oldest particles ever discovered.
NWA 482 is an extremely rare lunar meteorite because it contains only highland anorthosite crust minerals! It contains absolutely no detectable basalt minerals! The darker colored areas are impact melted plagioclase. The mineralogy of this meteorite strongly suggests its origin was on the Moon's far side and from very deep in the lunar crust. This meteorite contains only deep anorthosite crust minerals that have been melted and remelted by countless impacts over billions of years. Fusion crust is visible on the angled edge of this specimen. NWA 482 is totally unique among all the known lunar meteorites by containing only original lunar crust materials.

These Moon Dust display boxes contain genuine moon dust from the cutting of Lunar Meteorite NWA12593. The Moon Dust is securely preserved in a plastic container inside each display box.
Each display box contains 250mg of NWA 12593 lunar meteorite dust displayed in a black plastic glass top display box. These displays make wonderful gifts and come packed in a silver foil gift box.
NWA 8609 is a terrific lunar highland meteorite to examine with only the naked eye. It shows more than a dozen 2-5mm anorthosite clasts and countless smaller clasts. There are also a few 3mm size pyroxene clasts and some melt glass to see. Many of the larger clasts are themselves breccias containing olivine clasts within them. The huge clasts plus very little melt glass indicate this meteorite is from deeper in the regolith and was not part of the top surface regolith. This is the ideal lunar meteorite to enjoy with just the naked eye, but you can use a magnifying glass to view this meteorite again and again; and each time you will see clasts and crystals you never noticed before!

We have a nice selction of Seymchan Siderite meteorite for sale with it's very attractive etching. The Seymchan meteorite was found in 1967 in Magadanskaya oblast', Russia. The original two pieces discovered were sequestered in museums. Explorations of the find area have resulted in a signification number of additional masses being found. While many masses have olivine crystals characteristic of it's Pallasite classification, other pieces such as these are nearly solid metal.
NWA 998 is an extremely rare example of a Nakhlite and one of the very few available to collectors. Its dark olive or black pyroxene crystals and light olive or tan olivine crystals are easily seen without magnification. The serpentine surfaces of the olivine crystals definitely indicates this molten rock interacted with water; and the large crystal size indicates an extended cooling period in a thick lava flow. These very obvious features strongly suggest this liquid magma interacted with steam in a volcanic eruption and then slowly cooled in a thick lava flow near a shield volcano on Mars. As is typical of Nakhlites, this sample is friable and not suitable for group viewing or rough handling.

NWA 13366 is an incredibly rare Martian meteorite. Only four Peridotitic Shergottites are recognized, and NWA 13366 is one of them! Shergottites contain 0-15% olivine, but the Peridotitic Shergottites contain 50-60% olivine. NWA 13366 contains 60% olivine! Besides being extremely rare, Peridotitic Shergottites are important because they present additional evidence that the accretion of Mars did not produce a homogenous liquid mantle as occurred with the accretion of Earth. Instead, the Peridotitic Shergottites provide more evidence that the accretion of Mars produced a heterogeneous semi-liquid mantle with multiple zones containing many different mineral mixtures.
