What is solid gold?
According to the FTC, solid gold jewelry is technically any real gold jewelry piece that is not hollow inside.
So what is real gold jewelry?
Pure gold is 24 karat, which means 100% gold with no other metals or alloys added. However, pure gold is so soft that it is usually mixed with other metals (also called alloys) to make it more wearable.
The karats of gold depend on the number of other metals it is mixed with. Since pure gold is 24 karats, we always measure out of 24 parts. So 22k gold is 22 parts of pure gold and 2 parts of other alloys, 18k gold is 18 parts of pure gold, and 4 parts other alloys.
In the United States, real gold jewelry can be 24k, 22k, 18k, 14k, or 10k. 10k is the lowest amount of pure gold you can have before the metal becomes no longer considered gold. In the United Kingdom, 9k is the lowest amount of pure gold. Always doing things a little different aren’t we :)
What are those other metals or alloys?
In 14k gold jewelry, the metals that make up the other 10 parts or 41.5% depending on the color gold: yellow, white, or rose. Yellow and rose gold often have an alloy mixture of copper and sterling silver. Rose gold has more copper, making it more pinkish or rose. White gold often has nickel, zinc, and sterling silver, white metals that make it white gold. The exact percentages and mixtures are up to the caster or refining company. Each company has its own formula, which is why sometimes pieces from different designers both made in 14k yellow gold look slightly different!
How to care for solid gold?
14k gold can last a lifetime and become an heirloom piece of jewelry. Pure gold does not tarnish, but the additional metals in 14k gold can tarnish mildly over time. There are some chemicals like chlorine and abrasive acids that can damage gold. We recommend removing your 14k gold jewelry when swimming in chlorine or using cleaning products.
You can easily revive 14k gold to the original luster by cleaning your jewelry at home with a soft brush (we use a new soft toothbrush) and an organic cleaning spray (like Mrs. Meyers), when done rinse with warm water and air dry. Afterward polish with a soft jewelry polishing cloth.
