Blue Zircon Crystal cursor pack features a naturally occurring gemstone also known by its mineral name zirconium silicate. This crystal is created through heat-treating brown zircon, although only certain physical structures of brown zircon can be transformed into a blue one. Blue zircon is pleochroic - it can appear to have different colors when viewed from various angles. Often you will see shades of sea green in an otherwise cerulean blue zircon. Among all the popular blue gemstones, none can match the fire and brilliance of blue zircon. Its icy blue shades and festive sparkle make it the favorite stone of every human.
