When it comes to the metal used in your custom jewellery, you should consider quality and durability. A metal's purity or carat rating will affect its resistance to tarnishing and how well it stands up over time. Gold is one of the most popular choices for jewellery as it's strong, beautiful and holds its value. Still, other options are available such as sterling silver and platinum. No matter which metal you choose, ensure it's high-quality to keep your gemstones looking great for years.
