WHAT YOU NEED TO KNOW: WHAT IS 18K GOLD MIXED WITH?
We all know that 18K gold is made of gold, but what else is it mixed with to give it that beautiful yellow hue? Here are a few answers to that burning question.
18K GOLD COMPOSITION: WHAT'S IN THE MIX?
18k gold composition can be made up of a variety of metals, depending on the color (yellow, white, or rose). These metals are usually added to create a more affordable option than pure 24k gold and to increase durability. 18k gold jewelry items will have an alloy mix that typically contains 75% gold and 25% other materials.
WHY ADD IN OTHER METALS?
1) Copper: This element is popular in lower karat golds, like 14K and 18K, because it's less expensive than other metals and helps to make the alloy stronger. It also gives the metal a pinkish hue, making it more aesthetically pleasing. The amount of copper used in an 18K gold alloy depends on the desired color and strength of the jewelry. A heavy concentration of copper creates red gold. But, too much copper can also cause corrosion or discoloration over time, so jewelers must carefully balance how much they use.
2) Nickel: Nickel is often used in gold alloys because it gives the naturally yellow metal a bright white color and adds strength. However, some people can be allergic to nickel, so it's not always the best choice.
3) Zinc: Zinc is sometimes used in white gold alloys as well, but it's not as popular as nickel because it can make the metal more brittle.
4) Rhodium: Rhodium is a rare metal that's popular as a plating material for white gold jewelry. It gives the jewelry a brilliant white finish and makes it more durable.
5) Silver: Silver metal is sometimes used in gold alloys as well, but it's not as popular as copper because it is not as strong as copper. Silver also changes rose gold's color to create a whiter hue.
6) Palladium: Palladium is another precious metal that's sometimes used in gold alloys for its durability.
7) Platinum: Platinum is sometimes used in gold alloys for its strength and durability, but it's much more expensive than other metals, so it's not used as often. Platinum alloys have good stability, so the jewelry will not tarnish or change color easily. It also has excellent luster and malleability
8) Ruthenium: Ruthenium is a rare metal that's sometimes used in gold alloys for its durability and resistance to tarnishing.
As you can see, there are a variety of different metals that are mixed with gold to create different types of jewelry. The type of jewelry you choose will depend on your budget, style preferences, and allergies (if you have any). So now that you know what's mixed with 18K gold, go out and enjoy some beautiful jewelry!
