Just in time, Blue Zircon is the birthstone for December and here is an amazing old Blue Zircon set in a 10k gold ring. The mounting has the classic Art Nouveau curvy floral motif with the Blue Zircon simply set. The cherry blossoms set north, south, east and west.

The unique properties of a Blue Zircon are that this outrageously beautiful stone has a vibrant blue that is almost a teal blue. It is the MOST brilliant out of all the blue gemstones and it is double refractive which gives us an easy way to identify this stone. It is also fairly hard, rated at a 7.5 on the Moh's Hardness scale so it is a great stone to wear daily.
