Jacinth, derived from the English word for the orange precious stone, is a variety of zircon used as a gemstone. It is often associated with the biblical references in Exodus 28:19 and Revelation 21:20, where it is mentioned as a precious stone in the High Priest's breastplate and as a foundation stone of the New Jerusalem, respectively. The term 'jacinth' has been historically confused with other gemstones, particularly due to its biblical translations and interpretations.
