Blue Zircon, a natural gemstone, NOT to be mixed with Cubic Zirconia in anyway or form is a December birthstone. Despite it being a precious gemstone it is still yet very much affordable due to consumers' unfamiliarity with the gemstone. The truth however is that they are quite rare. Blue Zircon resembles a clean, tropical ocean with its brilliant pastel blue color. There is nothing quite like it if blue is your favorite color!
