18 kt gold: Composition and Characteristics.
18 kt gold is an alloy composed of 75% pure gold, while the remaining 25% is made up of other metals, such as silver and copper. Carats (kt) are the unit of measurement of gold purity: 24 kt indicates pure gold, while lower values represent alloys of different composition. 18 kt gold is particularly appreciated in jewelery because, in addition to preserving the elegance of pure gold, it offers greater resistance, making it ideal for everyday use.
Variants and Colors of 18 kt Gold.
Depending on the metals added, 18 kt gold takes on different colors. White gold, for example, is obtained by mixing gold with nickel or palladium, giving it a lighter shade. Rose gold, on the other hand, has a higher percentage of copper, which gives the alloy a characteristic pink colour.
Maintenance of 18 kt Gold.
Although 18kt gold is more resistant than pure gold, it can still get scratched or suffer light wear over time. To keep the jewel at its best brilliance and integrity, it is advisable to periodically turn to professionals for maintenance and polishing.
