Ancient Greek Bronze Age Rings Contain Rare Iron Linked to Meteorites

A detailed chemical examination of 91 archaeological iron artifacts from Greece and Crete uncovered 13 rings with notable nickel content, leading scientists to conclude that 10 of these were likely forged from meteoritic iron. The remaining three rings still await additional investigation.

This analysis, part of the forthcoming 2026 Journal of Archaeological Science article titled Iron in Greece in the second millennium B.C., was conducted by Matthieu Gounelle and Eleni Mantzourani. They employed portable X-ray fluorescence (XRF), a non-invasive technique, to assess iron artifacts sourced from 33 archaeological locations.

The majority of the examined items contained no detectable nickel, which the authors interpret as evidence that these were crafted from native ores subjected to early smelting processes. In contrast, meteoritic iron is characterized by a significantly elevated nickel concentration.

Nickel Found Solely in Ring Artifacts

All 13 nickel-containing pieces were rings or fragments thereof. Many were linked to large, ornately engraved metal plates, signifying their use as signet rings. Of those 13 objects, researchers classified nine as highly probable and one as quite probable meteoritic iron creations, while three remain inconclusive.

Interestingly, these rings often combined nickel-rich iron with other metals like gold, silver, or bronze, suggesting that the extraordinary iron was incorporated alongside luxurious substances.

The rings were discovered in significant archaeological contexts: elite burials, domestic residences, and a temple in southern Greece and Crete. One particular ring was retrieved from the Anemospilia temple on Crete; the other nickel-rich rings surfaced in tholos and chamber tombs among other valuable items.

Gounelle and Mantzourani suggest that these likely meteoritic iron rings symbolized status and power among the Minoan and Mycenaean aristocracy. Mantzourani highlighted that meteoritic iron was regarded as a precious and esteemed material reserved for exceptional objects and elite individuals.

Egypt Proposed as the Origin for the Meteoric Iron

Meteoric sources are scarce in Greece and Crete, prompting the researchers to hypothesize that the meteoritic iron was brought in from Egypt, where desert conditions enable a richer presence of meteorites. This proposition aligns with known Bronze Age trade routes without specifying a particular meteorite source or shipment.

Egypt also offers documented cases of meteoritic iron utilized in extraordinary artifacts of the Bronze Age era.

A 2016 investigation of King Tutankhamun’s iron dagger applied portable XRF to analyze the blade, revealing iron with 10.8 percent nickel and 0.58 percent cobalt. These results strongly suggested a meteoritic origin.

Discovered in 1925 within the layers wrapping Tutankhamun’s mummy, the iron blade was paired with an elegant gold handle and sheath. This finding supports the concept that ancient Egyptians prized meteoritic iron as an exceptional material for ceremonial objects.

Although this study does not confirm that the Greek rings used Egyptian meteoritic iron, the rarity of local meteorites alongside Bronze Age commerce between the regions makes Egypt a plausible source.

Meteoric Iron Rings Vanish by Late Bronze Age End

The research further noted a clear differentiation in the usage of meteoritic versus smelted iron during the Late Bronze Age. Rings crafted from nickel-rich meteoritic iron were finely made, whereas smelted iron typically featured in more utilitarian, less refined items.

However, this trend did not persist. After the 12th century B.C., no meteoritic iron rings have been discovered in the area. Mantzourani remarked that their disappearance coincides with the Late Bronze Age collapse and the conclusion of Mycenaean civilization in southern Greece.
