What's the difference between jacinth and zircon?

Jacinth


Definition:

  • (n.) See Hyacinth.

Example Sentences:

Zircon


Definition:

  • (n.) A mineral occurring in tetragonal crystals, usually of a brown or gray color. It consists of silica and zirconia. A red variety, used as a gem, is called hyacinth. Colorless, pale-yellow or smoky-brown varieties from Ceylon are called jargon.
