A rare lunar or Martian meteorite may fetch up to $1,000 per gram, or nearly 40 times the current price of gold. Tektites are glass objects created by melting Earth rocks when asteroids crash into the Earth. However, with 95% of meteorites (chondrites, iron meteorites), a meteorite with iron-nickel content attracts a magnet. The Campbell Geology Museum does NOT offer identification of potential meteorites. Meteorites are heavy, so a quality slice the size of a small dinner plate is worth thousands of dollars.
