Stony-iron meteorites consist of almost equal parts iron-nickel metal and silicate minerals including precious and semi-precious gemstones. They are considered some of the most beautiful meteorites. There are two different types of stony-iron meteorites: pallasite and mesosiderite.
How are stony-iron meteorites formed?
During the period of planet formation, mesosiderites originated by the low-velocity collisions of large metallic core fragments with the surface of a differentiated asteroid-size body . these collisions reduced mantles and crusts to small silicate fragments but left cores in the form of large, durable metal fragments.
How much is a stony iron meteorite worth?
Common iron meteorite prices are generally in the range of US$0.50 to US$5.00 per gram. Stone meteorites are much scarcer and priced in the US$2.00 to US$20.00 per gram range for the more common material. It is not unusual for the truly scarce material to exceed US$1,000 per gram.

What planet is a dirty snowball?
Comets are several miles in diameter, composed of rock, ice and other organic compounds, making them “dirty snowballs” in space, according to NASA’s near earth object program. They originate outside the orbit of the outermost planets and form elliptical orbits that pass close to the sun.
