Ice Blue Zircons have pleasing colors that are reminiscent of Aquamarine but with a lot more flash. Colors range from a pale blue to a medium pastel blue with a just a tinge of green in each shade.

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

Occasionally, Ice Blue Zircons will have tenebrescence. This is a rare property that only some zircons have. Gems stored in a dark area (e.g. safe) will look greyish or greenish-blue when they are first taken out. Once they are exposed to light they slowly turn into their ‘normal’ light blue color (usually within a few minutes). This is a fascinating phenomenon that can be repeated over and over again!

Tenebrescence is also known as reversible photochromism. This property is used in synthetic materials to manufacture photochromic or ‘transition’ sunglasses, which darken on exposure to sunlight.

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!
