The term bicolour refers to the two-colour nature of jewellery. However, it is not only the colour itself that is meant, bicolour can also mean that the piece of jewellery is based on different materials in different colours. Bicolour jewellery usually means a product that consists of white gold and yellow gold. This means that two different gold alloys have been brought together in this item and that they can also be visually distinguished from each other. But other materials can also be gold-plated or IP-coated in different colours. Besides the popular colours silver, gold and rosé, there are also black, gunmetal and others. In this way, bicolour jewellery can be used to create contrasts and a high-quality and visually appealing result. Bracelets and necklaces are popular pieces of bicolour jewellery, but rings can also be designed in this style.
