Blue Zircons have a pleasing blue color with just a tinge of green. This is one of the most popular color in Zircons, and they are available from light to medium shades. More intense colors are rare.

They are not to be confused with Cubic Zirconia (CZ) which is man-made. Blue Zircons are mined in Cambodia. They come out of the ground in a brown to brownish-red color and are then heated to their blue colors.

The name ‘Zircon’ derives from the Persian word ‘zargun’ meaning golden hued. Zircons (and possibly other gems) in the pinkish-purplish-reddish color range were historically referred to as “Hyacinth” or “Jacinth”.

Zircons have extremely high dispersion of 0.038, which is the optical property that splits light into its component colors. That explains all those flashes of color when we look at these beautiful gems.

Their refractive index (RI) is also very high ranging from 1.81 to 1.98 and they are durable with a hardness of 7-7.5 for ‘high’ zircons.

Natural Zircons are still available at a fraction of the price of most other gemstones, making them the last undervalued gem!

Zircon is December’s birthstone, providing a lot of color choice for December birthdays!
