Zircon is the birthstone of the month of December.

The first thing to be understood while talking about zircon is the name. Zircon is easily confused with the word Zirconia, cubic Zirconia. Zirconia is the synthesized material  of the crystalline form of  zirconium dioxide (ZrO2).

Natural Zircon is Zirconium Silicate (ZiSiO4). It is a mineral which belongs to neosilicates. The name zircon has derivative in many languages like Zargun in Persian, Zargono in Syrian, Zargun in Arabic all of which means vermillion. Vermillion means reddish or vivid red. The yellow variety of zircon was called as hyacinth, from greek. Lately the name was restricted to yellow zircon.

The Specific gravity is 4.6–4.7 and the refractive index is 1.930 - 1.987. Because of their uranium and thorium content, some zircons might undergo metamictization which changes the mineral to be amorphous.The Moh's hardness for zircon is 6.5 to 7.5. Due to this the refractive index is n? = 1.925-1.961 ne = 1.980-2.015, 1.75 when metamict, zircon is birefringence which means double refraction. Light splits into two rays and this doubling effect is also seen in sphene.
