"It is heavy it is made of iron and nickel, it is 88.5 percent iron and 11.5 percent nickel", says Sirbescu.
"I could tell right away that this was something special", she said, noting that it's the sixth-largest meteorite found in MI. This is the rags-to-riches story of a rock from outer space.
The meteor that blazed through MI this January changed his life's trajectory as he read accounts of people finding and selling small pieces of the meteorites. The farmer then told him that he and his father saw it fall at night during the 1930s, adding that since the meteorite was part of the property, the man could have it.
A man has discovered a rock he's been using as a doorstop for 30 years is a meteorite worth more than $100,000.
The man reportedly hasn't figured out exactly where the meteorite will end up, but a number of institutions are apparently considering purchasing it from him for display.
But after hearing that shards of a meteorite that crashed in Michigan had sold for a high price, Mazurek took his "doorstop" to be appraised at Central Michigan University.
The Smithsonian and another museum in Maine have already expressed interest in the rock, and Sirbescu called it "the most valuable specimen I have ever held in my life, monetarily and scientifically".
While a space rock's size and what elements it's made from determine its value, all meteorites are worth something, and there's a large market for collectors. They say it's worth around $100,000, and is the sixth largest meteorite found in MI.
Most meteorites typically consist of approximately 90-95% iron.
She said she felt excited to play a role in identifying the meteorite.
The unnamed man is reportedly actively looking to sell the meteorite, but has not yet found a buyer.
Regardless of how much that is, Sirbescu feels that she, CMU and her students already have benefited.
The meteorite's anonymous owner is promising to donate 10% of sale proceeds to the university.
"Just think, what I was holding is a piece of the early solar system that literally fell into our hands", she said.
