Zircon (/ËzÉrkÉn/ or /ËzÉrkÉn/ ; including hyacinth or yellow zircon) is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate and its corresponding chemical formula is Zr SiO4.ircon is ubiquitous in the crust of Earth. It occurs as a common accessory mineral in igneous rocks (as primary crystallization products), in metamorphic rocks and as detrital grains in sedimentary rocks. Large zircon crystals are rare.
Common brown zircons can be transformed into colorless and blue zircons by heating to 800 to 1000 Â°C. However, only some brown materials have the appropriate physical structure to turn blue when heated, typically only deposits found in Southeast Asia - which is why most blue zircon comes from the Ratanakiri Province in northeastern Cambodia, where we are, or Burma.
