Alloy and Metals
We often overlook the privilege of being able to purchase jewelry whenever we desire, including the freedom to choose the metal for our rings. The manufacturing of gold rings involves significant effort, with various alloys and metals playing crucial roles in their production.
Alloys are metals combined with other elements to enhance their strength and resistance to corrosion. They are used because pure metals often lack the necessary properties for certain applications. For example, while iron is suitable for construction, steel—a stronger, more durable, and rust-resistant alloy made with carbon and other materials—is preferred. Aluminum, lightweight but soft in its pure form, benefits from alloying to improve its properties. In jewelry making, alloys such as copper, iron, nickel, silver, tin, zinc, cadmium, titanium, and manganese are commonly mixed with gold to create desired characteristics.
These alloys not only enhance the strength of gold but also influence other properties. Some gold engagement rings can cause a dark stain on the wearer's finger or trigger allergic reactions like rashes and blisters. Despite these considerations, gold remains highly versatile and popular. It can be crafted into various shapes, and if it is 18k or higher, it maintains its luster without tarnishing or causing irritation. White gold engagement rings, often made from gold alloyed with lighter metals and plated with rhodium, are a preferred alternative to platinum due to their appearance and cost-effectiveness. Classified as a platinum metal, white gold is the second whitest precious metal after silver.
