In 1985 the Middleham Jewel was found in the grounds of the castle by a man who was using a metal detector in the area. The Middleham Jewel is a mid-15th century 68 gram gold pendant with a 10 ct. blue sapphire stone. One side of the diamond shaped pendant is engraved with a representation of the Trinity and the other with a Latin inscription indicating that the pendant is a charm against epilepsy. The sapphire may represent heaven. It has been acquired by the Yorkshire Museum in York for £2.5 million.
