Why do some meteorites cost far more than gold?
Because some kinds are far rarer than gold. Thousands of tonnes of gold are mined every year, but some meteorite types are known from only a few kilograms worldwide, and collectors and institutions compete for them.
Gold feels like the ultimate symbol of rarity, but on a world scale it is not that scarce. Mines produce thousands of tonnes every year, and far more has been accumulated over history. Gold is also uniform: one gram of pure gold is identical to any other, so its price is set by a huge global market.
Meteorites work differently. Each one is a unique sample from somewhere else in the Solar System, and some kinds are exceptionally scarce. A few meteorite groups are known from only a handful of stones, sometimes adding up to just a few kilograms in all the world's collections. Martian and lunar meteorites, pieces of famous historic falls, and fresh witnessed falls of unusual types are all limited in supply. When many collectors and institutions want something that exists in tiny amounts, the price per gram can climb far above that of gold.
Scientific and emotional appeal adds to this. A slice of Mars, a fragment that fell in front of witnesses centuries ago, or a meteorite holding grains older than the Sun has a story that no bar of metal can match. Beautiful features, such as a cone-shaped oriented stone or the crystal pattern in an etched iron, add more.
It is important to keep perspective, though. Most meteorites are common types and are worth far less than gold. The market is small, prices are set privately by sellers and buyers, and values can fall as well as rise, for example when large new finds come to light. That makes meteorites a poor choice for anyone hoping for a financial return. Their real worth lies in what they reveal about the Solar System and the wonder of holding one.
