29.7g Genuine Martian Meteorite with Aqueous Alteration - FULL SLICE - Pending Classification - Scientifically Studied Rock From Planet Mars

You are viewing the newest genuine Martian meteorite brought to the Interstellar market that originated on Planet Mars. This is a true chunk of the Red Planet, studied by leading scientists in the field of Meteoritics. It has been determined that this stone has evidence of aqueous alteration present within the pyroxenes that occurred while on its parent body. This signifies something we’ve already known to be true, but fascinating nonetheless - the presence of water on Mars.

The total weight of discovery is only 358g, making this a single stone find! It is currently under classification, and is stunningly beautiful in every direction you turn it. This is surely a front-of-display meteorite in your collection. 

Please note: this meteorite is still under scientific classification. The study and full writeup will take anywhere from 4-6 months to complete.  You will still receive a certificate of authenticity, as the stone has already been confirmed to be from the parent body mentioned on this listing. This is a fantastic time to jump on board with this stone.  Should there be a discovery of anything further of scientific importance with this stone, you will be in at ground zero.

How do we know it’s from Mars?

Just like our moon, Planet Mars also encounters Meteoroid impacts quite often. With enough velocity, chunks of Mars can eject and escape its own gravity, sending them on a journey through interplanetary space. If the sun or Earth’s atmosphere doesn’t burn them up and they survive their violent descent to Earth, they have the chance of being discovered, studied and classified by leading scientists in the field of Meteoritics! Using microscopic (thin sections), chemical, and isotopic analysis, scientists compare the stone’s composition to known planetary materials.

But the most definitive evidence comes from gas trapped inside the rock! 
Martian meteorites contain tiny bubbles of gas sealed within glassy inclusions. When analyzed using mass spectrometry, the gas composition matches the Martian atmosphere exactly as measured directly by NASA’s Viking landers in the 1970s and confirmed by later missions like Curiosity. The match is so specific that there's no other natural source on Earth (or elsewhere) with the same gas profile.
