Before You Buy: What I Wish I’d Known About Jewelry Materials

I used to buy jewelry mostly based on what I could see and whether I liked the design. But over time, I started noticing that some of my jewelry would lose its color, become dull, or simply not look the same after a few months and several wears. I didn’t really understand why.

It wasn’t until I started learning more about jewelry making and production that I realized jewelry is about more than just how it looks. It’s also about what it’s made of, how it’s made, and what’s underneath the finish. These things can make a big difference in how jewelry wears over time and whether the material itself has any lasting value.

I wish I had known this before buying some of the jewelry I own. So here’s what I’ve learned about what your jewelry is actually made of.

Before making a purchase, I think it’s always worth checking the base material. It can tell you a lot about how a piece will wear, how to care for it, and whether the metal itself has any material or resale value.

Most Precious Metals Can Be Recycled and Have Material Value

Not all jewelry has the same value once you’re done wearing it. Fashion jewelry made with common base metals is generally valued for its design rather than the material itself. Precious metals are different. They can often be melted down, refined, and reused, which gives them value beyond the piece of jewelry itself.

Here are some precious metals you’ll commonly find in fine jewelry.

Gold is valuable in many forms, from 10k to 24k and in colors like yellow, white, and rose gold. 24k gold is almost pure gold, so its material value follows the market price of gold, which can fluctuate over time. Gold from 10k to 22k is mixed with other metals to make it stronger and more suitable for jewelry. Generally, the higher the gold content, the higher the material value.

Platinum is naturally a silver-white metal and is usually around 90 to 95% pure in jewelry. It’s dense, durable, and valuable. Unlike many base metals, platinum can be melted down and refined, so the metal itself retains meaningful value.

Palladium is another precious metal with a naturally silver-white color. You may see 950 Palladium, which means the piece contains 95% palladium. It’s less common than gold, silver, or platinum, but it is still a valuable precious metal that can be used in jewelry and white gold alloys.

Silver can also hold material value, especially when it is marked as sterling silver (.925) or fine silver (.999). Sterling silver contains 92.5% silver, while fine silver is 99.9% silver. Like other precious metals, silver can be melted down, refined, and reused, so it can still have value even when the original piece is no longer wearable.

Base Materials With Little to No Resale Value

Many fashion and everyday jewelry pieces are made with other base materials. This doesn’t mean the jewelry is bad or not worth buying. These materials are often chosen because they are affordable, easy to work with, lightweight, or better suited for certain designs.

The main difference is that you’re generally paying for the design and craftsmanship rather than the material itself. Once the piece is no longer wearable, the base metal usually has little to no resale value.

Here are some of the most common ones.

Brass is one of the most common base materials used in jewelry, especially for gold-plated pieces. It has a naturally warm, yellow tone, which makes it a good base for gold plating. It’s affordable and easy to shape, making it popular for statement and detailed designs. However, brass can tarnish or darken over time and generally has little to no resale value as jewelry metal.

Copper has been used in jewelry for centuries. Its warm, reddish color gives it a more earthy or vintage feeling. It’s very affordable and easy to form, which makes it popular for artistic and fashion jewelry. Copper can tarnish fairly quickly and may leave a greenish mark on the skin with prolonged wear. Like brass, its value is mainly in the finished piece rather than the material itself.

Stainless steel has become popular in everyday jewelry, especially for modern and minimalist designs. It’s strong, durable, resistant to rust and corrosion, and requires relatively little maintenance. It’s a practical choice for pieces you want to wear regularly, but the metal itself generally has little resale value.

Titanium is known for being very strong while also being incredibly light. For jewelry, especially earrings, that can be a great combination. You can have a larger-looking piece without feeling as much weight on your ears. Titanium is also corrosion-resistant and generally well tolerated by people with sensitive skin. It’s mainly chosen for its strength and comfort rather than its resale value.
