December Birthstone Blue Zircon Earring
It is a round Tiffany cut turquoise 4mm, claw set silver stud. Zircon, Tanzarite and Turquoise all lay claim to being a December birthstone. Turquoise is a relatively soft gemstone, and can be easily scratched and broken. This porous opaque stone is easily discolored by oil and pigments, and changes color when it loses some of its water content.
A sky blue shade in turquoise is due to the presence of copper, while iron gives it a greener tone. They each carry a unique blue tone making it a perfect frigid December weather. Suitable for zodiacs Sagittarius and Capricorn, these earrings are Nickel free and hypoallergenic for sensitive ears.
