Lost onyx stone believed to be an ancient gem from the breastplate of the High Priest of Jerusalem is ‘found’ after being ‘missing for 1,000 years’

A small onyx stone believed to have been worn in the sacred breastplate of the High Priest of Jerusalem may have been found after being missing for more than 1,000 years.
A sardonyx gem, thought to have been one of two that were set in gold on each shoulder of the breastplate and deemed to be ‘forms of divine communication’, was discovered in South Africa.
The owner claims the stone was given to a distant ancestor as a reward from the High Priest in 1189 and has been passed from generation to generation of the family since.
