In 1952, the Jewelers of America organisation added the Zircon to the list of birthstones for the month of December. It is believed that the Zircon attracts prosperity.

The name for the Zircon stone seems to derive from the word "zargoon" which in Arabic means "vermilion" (cinnabar powder used to obtain deep red paint) and in Persian means "golden color".

In the 18th century, the colorless zircons found in Matara (Sri Lanka) were erroneously considered to be diamonds of low quality and denominated "Matara diamonds."
