Terms to know

Let’s talk about some jewelry vocabulary.

Karat: Karat is a measurement of the fineness (purity) of gold jewelry. It is measured in 24 parts; with 1-karat being 1 part gold and 23 parts other metals. Whereas 24-karat is 24 parts gold and no parts other metals. Abbreviations for karat are kt, k, and K

Alloy: Alloy is a metal mixed with another metal. Gold alloys are metals mixed with gold to create gold jewelry. Alloys are the “other metals” that make up gold jewelry.

Carat: Not to be confused with karat, carat measures the weight of diamonds and colored gemstones like ruby, sapphire, or emerald. 0.2 grams are equal to 1 carat. The abbreviations for carat are ct and CT.

24-Karat Gold: What’s the Big Deal?

Other than mining it out of the ground, 24-karat is the purest gold possible. “Pure Gold” is a very alluring title, but it is important to understand the characteristics of 24-karat gold. Check out some pros and cons of 24-karat gold to decide if it is the best jewelry for you.

Karat Values: Decoding 10K, 14K, and 18K Gold

The color, sturdiness, and price of gold jewelry are all dependent on karat value. All karat values of gold are “real gold” they all have different percentages of gold. Karat values can range from 1 to 24 but 10-karat, 14-karat, and 18-karat are the most common values available in jewelry pieces.

14-karat gold is the most popular karat value in the United States. 14-karat gold can be alloyed with other metals to create all different colors of the rainbow. It is hypoallergenic jewelry; with the proper care, it can last a lifetime. 14-karat gold is a great option for engagement rings and other items of daily wear.

Alloys: What About Those Other Metals?

Pure gold is extremely soft, adding alloys increases the durability and changes the color of gold. Every karat value below 24-karat gold uses alloyed metals.

Common gold alloys include:

Copper: Copper adds a red color to the gold. It is used in combination with silver to make rose gold.

Platinum, palladium, zinc, and nickel: These metals “bleach” gold or make it lighter. Most metals bleach gold but platinum, palladium, zinc, and nickel create white gold.

Iron: Iron adds blue to gold. Iron may also be used in combination with copper to make a grayish gold.

Silver: Silver adds green to gold. Silver can be used in combination with cadmium and copper to make an even deeper green color.

Aluminum: Aluminum turns gold purple.

Karats: How to Find the Value

The best way to find the karat is by checking for a stamp on the jewelry. This might be on the inside of a ring or on the clasp of a necklace or a bracelet. The stamp will either explicitly say the karat count (denoted with K, kt, or k in the U.S.; CT or ct in the UK and Ireland) or will list a series of numbers. These numbers represent percentages that correspond to karat markings. For example, 417 is 41.7% gold or 10-karat gold.

There are a couple options to find the karat value of jewelry if there are no markings present or verification is needed. Jewelry appraisers are trained professionals that use technology and observation to discover the karat value of gold. At-home methods of discovering the karat of gold are available but not nearly as accurate. It is important to see a jewelry appraiser whenever possible.

Observation: Since 24-karat gold has very little alloyed metal, it will always be a yellow-gold color. Any other colors present in jewelry are indications that the gold is not 24-karat. It is near impossible for the untrained eye to tell the exact karat count through observation alone.

Best at-home method: Gold testers are widely available online. These testers can determine the exact karat of gold. Some are more accurate than others, make sure to read the reviews to verify the gold tester will work.

In-pantry at-home method: This method can determine whether jewelry is pure gold or not. Put vinegar on your jewelry. A color change means the jewelry is less than 24-karat, simply gold-plated, or has no gold at all. Jewelry will turn black if it is just gold plated.

Carats: Are They Different from Karats?

Diamond carats are very different from gold karats. Carat is a measurement of the weight of gems, mainly diamonds (0.2g = 1 carat). Diamond carat prices are unique because they are controlled by “magic numbers” which are markers determining the points where diamond prices increase. The magic numbers are: 0.90 cts, 1.00 cts, 1.50 cts, 2.00 cts, 3.00 cts, 4.00 cts, and 5.00 cts. As a buyer, it is vital to know the magic numbers to get the best price for the best diamond. Purchase diamonds that are at the top of the magic number range. Buy a 0.99 carat diamond rather than a 1.00 carat diamond. They look the same size, but 0.99 carats is much cheaper!

The 4Cs are the golden rules when it comes to finding the perfect diamond. Carat, Cut, Clarity, and Color. Here is a quick rundown of the rest of the 4Cs.

• Cut: How the light will hit the curves and edges of a diamond. Essentially, how the diamond will sparkle.
• Clarity: This refers to how clear the diamond is, or how many impurities it contains.
• Color: Colored diamonds can be pink, blue, yellow, and more. Some diamonds are near colorless with light shades of yellow.

Allergies: How to Find Hypoallergenic Jewelry

Those pesky allergies and jewelry. The higher the karat value, the less likely the jewelry is to cause a reaction as it would contain less allergy-inducing metals. 14-karat gold is a great option for hypoallergenic jewelry, it strikes a balance between price and karat count. Look for gold that is nickel-free to reduce allergy risk.

Style: How to Mix and Match Karats and Colors

Jewelry of different karat values and colors can be mixed to match your personal style. Keep in mind, different karat values of jewelry have different colors. Be careful when trying to match jewelry colors exactly.

Learn different color options when mixing and matching various karat values of jewelry. Wear purple gold earrings and a blue gold necklace to complement it. You can also try different shades of gold, such as rose and yellow gold.
