People love gold—and they have for a very long time. While the gold adornments preferred by Egyptian Pharaoh Tutankhamun (aka: King Tut) circa 1323 B.C. differ from those worn by today’s style influencers, gold is as prized now as it was then. It’s no wonder that ancient cultures all over the world forged gold into jewelry and structures to portray status and wealth. Today, gold is a very popular choice for engagement rings and other fine jewelry.
As the most malleable of all precious metals, gold is an excellent choice when crafting designs with very intricate details. Plus, it’s resistant to rust, tarnish and corrosion. Pure gold is too soft for everyday wear, so it’s alloyed with a mixture of silver, copper and a trace of zinc, to give it strength and durability. This hardens the final product enough to last for many generations.
Karatage, denoted by a number followed by “k”, indicates purity, or how much of the metal in a piece of jewelry is gold. Karatage is expressed in 24ths, making 24k gold the highest karat gold. It has a rich and luxurious gold-yellow color, but unlike 14k or 18k gold, it’s far too malleable for everyday wear. If you’re unsure what karat your jewelry is, you can find out by looking for a number followed by a lower case “k” stamped somewhere on the piece.
Gold is commonly stamped with what’s known as a hallmark. The hallmark indicates the amount of pure gold content, and sometimes denotes the date of completion and country of origin. And under federal law, gold jewelry must be accompanied by a maker's mark or registered trademark.
We carry jewelry that’s crafted in both 18k and 14k gold. Our 18k gold is an alloy of 75% gold with other metals to make it strong enough for everyday wear, and our 14k gold is an alloy of 58.3% gold and other metals. The minimum karat that is allowed to be sold as gold jewelry in the U.S. is 10k—an alloy of 41.7% pure gold. If you’re one of our European customers, you may be accustomed to a different gold karat scale. 585 is equivalent to our 14k gold, while 750 is the same as our 18k gold.
Although it’s true that the color of pure gold is yellow, gold jewelry or objects are almost always alloys. The metal they are alloyed with changes their color to a variety of shades depending on:
Our fine jewelry comes in 3 colors: yellow gold, white gold and rose gold.
A mixture of silver, copper, pure gold (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.
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 Diamond BAYOU.
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.
For yellow gold and rose gold settings, Diamond BAYOU uses platinum ring heads to secure center diamonds. All designs in 14k white gold use 14k white gold ring heads which have the strength and durability required to keep a center stone safe. 14k white gold is a very popular option with our customers as it has a similar look to more expensive platinum settings, but a more affordable price tag.
Gold is traded on a public exchange and therefore the price is subject to many external influences. That’s why the price of gold jewelry is largely dependent on three factors:
24 karat = 100% gold
22 karat = 91.7% gold Both 24k and 22k are considered too soft for fine jewelry, though prized and worn in some cultures.
18 karat = 75.0% gold Considered to be the luxury end of fine jewelry.
14 karat = 58.3% gold Ideal for fine jewelry, balancing wearability and value.
10 karat = 41.7% gold Not available at Diamond BAYOU.
The karatage that’s right for you may be a personal preference or a matter of budget. Both 14k and 18k jewelry from Diamond BAYOU are sure to impress, so you don’t necessarily need to go for the higher karatage. Here are some factors to consider when deciding which to choose:
Prolonged or repeated exposure to chlorine or other chemicals in cleaning products can harm gold jewelry. We recommend that you remove your jewelry when gardening or cleaning to reduce abrasions and prolong the luster. To clean gold jewelry, use a solution of warm water and detergent-free soap with a soft-bristled brush. Then, polish it with a specialized cloth or cleaning solution. When not worn, store your gold pieces in soft cloth bags or the original box to help prevent scratches.
