The process: The colour on the earrings is visible due to a carefully executed process of anodizing titanium where reflected light is seen as a colour of the object. Anodizing titanium is an electrochemical process where a thin transparent oxide layer is formed on the surface of the titanium. A phenomenon called light interference occurs – commonly seen as a colour spectrum on soap bubbles for example. White light consists of colour light waves. The light reflects back from the surface of the titanium jewellery – some from the oxide layer, some from the titanium surface beneath. The reflected light waves interfere with each other, some wavelengths get reinforced, some cancelled out. Which colour wavelengths end up together depends on the thickness of the transparent oxide layer. So you end up seeing coloured light waves as the colour of the object. There is no paint, no pigment, just light.
Note: Due to differences in computer screens colours may vary slightly from the picture. Some discolouring of the jewellery may occur when coming to contact with grease, e. g. fingerprints etc. Washing with soap will restore the original colour. You can find a detailed description of how to take care of your titanium jewellery in the delivery package. If cared for, your titanium jewellery will last forever.
