diadem

Among the eight items stolen were diadems, necklaces, ear-rings and brooches adorned with thousands of diamonds and other precious gemstones.

Crowns and diadems - which were stolen in the heist - can easily be broken apart and sold in small parts.

Also stolen was a diadem that once belonged to the Empress Eugenie, which has nearly 2,000 diamonds; and a necklace that once belonged to Marie-Amelie, the last queen of France.

According to the authorities, eight items were taken including diadems, necklaces, ear-rings and brooches.

The greenstone ornaments are typical of the Late Classic period and the mask and diadem are known to be exclusive to Maya royalty.
