Platinum is a popular choice for wedding and engagement rings due to its hardness, rarity, and naturally white sheen that will never fade or change color. Platinum is heavy, strong, and naturally hypoallergenic. It is the best choice if you have the budget, as it will last a lifetime and beyond.
White gold jewelry uses pure gold alloyed with other white metals such as palladium and silver. White gold jewelry is plated with rhodium to give it that brilliant white luster. Rhodium plating is hypoallergenic and helps to protect the white gold. Although durable, rhodium wears away over time. Re-plating is a simple process that can be done to restore whiteness at any time.
Yellow gold is the traditional choice for wedding rings. A mixture of pure gold, copper, and silver gives yellow gold jewelry its signature warmth. The most common gold purity levels are 10k (karat), 14k, 18k, and 24k. The color and hardness will differ depending on the karat of gold you choose.
Rose gold is a delicate mixture of classic yellow gold, silver, and copper metals. The silver and the copper combine to create the pink hue we know and love when it comes to rose gold. Rose gold is often used in bi-colored rings to offset the more traditional white or yellow gold. Like yellow gold, depending on the carat you choose, the color and hardness of the ring will differ.
Silver is one of the longest-standing precious metals used in making jewelry. It is a popular choice as it is very malleable and one of the most inexpensive precious metals. It is important to note, however that silver will tarnish to a dark gray color and does scratch easier than other metals due to the softness of the metal. Silver metal is generally too soft a metal to be used for pieces such as wedding rings, which are meant for daily wear.
