Green/Blue Zircon Crystal December Birthstone, 316L Surgical Stainless Steel.
December's birthstone is the colourful green and blue zircon crystal. This simulated zircon crystal is framed in a silver-coloured rub over bezel setting and measures 4mm in diameter. They are made using 316L surgical stainless steel.
Our stainless steel is a surgical steel with the 316L designation. Just like any other steel, this steel contains nickel. However, the nickel release rate for 316L surgical stainless steel is well below the allowable value given in the EU nickel directive, which makes it hypoallergenic and well suited to use in piercing studs and fashion earrings. This steel is also used for medical purposes, such as surgical implants, which remain in the human body for a lifetime without any harmful side effects.
