These sterling silver CZ birthstone ear studs feature a 4mm round setting with a 3mm cubic zirconia to represent the equivalent birthstone.
The setting is 2mm deep with an 11mm post of 1mm wire thickness. The setting has an open back.
The stone is a 3mm Cubic Zirconia (CZ). which is a manmade crystalline form of zirconium dioxide, developed as a substitute for diamonds. It is more durable and has better light refraction than glass alternatives. Some colours may change tone or hue in different lights. Due to these being representative of the gemstone for each birth month some of the months have similar colours as is the case with the natural stones.
If you have had your colours analysed, they are suitable for a winter or summer palette.
