Important Differences between 22k Gold and 24k Gold

22k Gold

22k gold is a type of gold alloy composed of 91.67% pure gold and 8.33% other metals, often copper and silver. This karat of gold is valued for its rich, warm color and is commonly used in the crafting of high-quality jewelry. The inclusion of alloy metals enhances the durability and strength of the gold, making it suitable for intricate designs and detailed craftsmanship. Due to its high gold content, 22k gold is softer than lower karat alloys, making it more prone to scratches and wear. It is a popular choice for traditional and cultural jewelry, reflecting both intrinsic value and cultural significance.
