What Is Yellow Gold?
A mixture of silver, 銅, 純金 (and a trace of zinc) gives yellow gold jewelry its rich shine. Although the percentages of each metal used to create the alloy vary, all formulas starts with 75% pure gold for 18k gold and 58.3% for 14k gold. The result gives off a classic warm glow that makes an especially good setting for lower color grade diamonds with a faint yellow tint.

If you’re interested in 14k yellow gold, which is slightly less rich in color than 18k yellow gold, it’s important to note not only the difference in color between the two karatages, but also the difference in durability and hardness. 18K is softer and will therefore show scratches more readily. 14K is harder which makes it a little more resistant to scratching.

What Is White Gold?
In order to give white gold jewelry its modern silvery-white color, pure gold is often alloyed with a mixture of nickel, or palladium and silver, plus other whitening alloys. The piece is then plated (meaning it’s covered with a layer of another metal) with an extremely hard element called rhodium. While rhodium plating is relatively long-wearing, some occasional replating may be required. It’s not uncommon after a few years to see a slight champagne-colored tint in your white-gold jewelry. This can be a sign that your jewelry needs replating to restore its original whiteness. We recommend routine cleaning and annual maintenance. Please contact our diamond and jewelry experts if you’d like to replace a ring purchased at Blue Nile.

What Is Rose Gold?
The romantic pink hue of rose gold jewelry is created by using a copper alloy. The more copper in the alloy, the rosier the hue. Rose gold has the same amount of pure gold as yellow or white gold. What’s different is the ratio of other metals that make up the remaining percentage of the alloy mix. Rose gold is a beautiful and unique choice for engagement rings, and its modern-vintage appeal has been a hot trend in the last few years. The preference of one karatage over another comes down to whether people want a lighter (18k) or slightly deeper (14k) rose color for their setting or band.
