White metals are popular options for modern wedding band designs, and cobalt is one of the newer gold alternatives. Cobalt jewelry has the luxurious look of platinum without the high price tag. This type of wedding band is a great choice for a couple on a budget, but it's important to understand the basics before you buy.

Buyer's Guide to Cobalt Wedding Bands

According to Chemistry Explained, cobalt became an official element in the periodic table in 1735, but its use in jewelry is very recent. By blending this element with other metals, manufacturers can create a beautiful and durable alloy that is perfect for wedding jewelry. Since cobalt's introduction to the jewelry market, it has become a popular alternative to other metals.

Understanding the Cobalt Alloy

The cobalt alloy used in jewelry is commonly called "cobalt chrome." On its own, cobalt would not be appropriate for jewelry, but in combination with these other materials, it takes on new properties. Titanium Kay reports that cobalt chrome is constructed of eight different materials:

  • Cobalt
  • Chromium
  • Tungsten
  • Iron
  • Silicone
  • Manganese
  • Molybdenum
  • Carbon

This results in a durable, attractive alloy with many advantages.

Benefits of Cobalt Rings

There are a number of important benefits to using cobalt alloy in wedding jewelry:

  • Cobalt is very bright and attractive, and it has a white-gray color similar to more expensive precious metals. In addition, the white color is trendy and goes with other white metal jewelry like sterling silver and white gold.
  • Cobalt alloys are extremely durable and are used in the aerospace industry. Rings made with this material are scratch-resistant.
  • In its alloy form, cobalt is hypoallergenic. In fact, this alloy is used for making medical devices. This makes it a great choice for people with metal allergies.
  • As an alloy, cobalt chrome is extremely stable and doesn't tarnish. A coating is not required to maintain the white color and high shine, and your ring will look brand new for years to come.
  • Cobalt jewelry can be resized, unlike other durable alternative metals.

Considerations Before Choosing Cobalt

Before you decide to purchase a cobalt wedding band, there are a few considerations to keep in mind.

  • Cobalt wedding jewelry may be difficult to find in some locations, and there are not as many ring designs available as other more popular metals. However, if you shop online, you'll still find a good selection.
  • More designs are available for men than women, but there are rings for both genders.
  • Rings made out of cobalt are heavier than titanium, platinum, or gold rings. This isn't a problem for many people, but if you dislike the feel of heavy jewelry, cobalt may not be for you.
  • Since it does not bend and stretch the way gold and other metals do, a cobalt ring will have to be cut off if it can't be removed during a medical emergency.

Durability of Cobalt

According to Tungsten World, cobalt chrome rates between 7 and 8 on the Moh's hardness scale. This makes it a more durable choice than soft precious metals like sterling silver, gold, and platinum. This hardness means that cobalt chrome can't be made into some of the intricate designs of other precious metals, but it also means it's more scratch resistant.

Cobalt is harder and more resistant to scratches than titanium, another popular alternative metal. However, cobalt chrome isn't quite as hard and scratch resistant as tungsten carbide. Additionally, tungsten carbide can shatter when dropped on a hard surface, but cobalt rings will not.

Cost of Cobalt Wedding Rings

CNN Money reports that cobalt wedding bands are among the most cost-effective choices for today's couples. A typical cobalt band costs between $200 and $300, while a similar platinum band would cost about $1,900. This makes cobalt an attractive option.
