Iron Meteorite from Campo del Cielo, Argentina - Pendant with Chain in 925 Sterling Silver

An iron meteorite pendant with chain from Campo del Cielo, Argentina in 925 sterling silver. This jewelry set transforms 4.5 billion years of solar system history into a wearable form.

Radiometric dating of iron meteorites uses the rhenium-osmium isotope system: the radioactive isotope ¹⁸⁷Re decays to ¹⁸⁷Os with a half-life of 41.6 billion years. Measuring the isotope ratios allows for extremely precise age determination.

Campo del Cielo material dates back to the early solar system, approximately 4.55 billion years, almost simultaneous with the formation of Earth (4.54 billion years) and older than the oldest known minerals on Earth (zircon microcrystals from Western Australia, 4.4 billion years).

The included sterling silver chain is ready to wear.
