Gold has captivated humanity for a long time, serving as a symbol of wealth, beauty, and status across cultures. This precious metal’s value stems from its rarity, malleability, and resistance to corrosion. In today’s market, gold remains a popular investment option and a cherished material for jewelry and collectables. However, not all gold is created equal, and understanding its purity is crucial for both buyers and sellers.
When it comes to gold, purity is often expressed in karats. But what exactly does “gold karat” mean? Understanding gold karats is essential to make informed decisions and ensure you’re getting the correct value for your items.
As experts in precious metals, coins, and collectables, all team members at CV Coins & Collectables understand the importance of educating our customers about the gold they’re buying or selling. That’s why we’ve created this comprehensive guide to help you gold karats with confidence.
Precious metals are measured in Troy Ounces. There are 31.1035 grams to a troy ounce. Regular Avoirdupois ounces are only 28.35 grams to an ounce. Troy ounces (12 ounces= 1 troy pound) are 10% heavier than a regular ounce (16 ounces=1 Avoirdupois pound1. Sounds odd? Avoirdupois is what we use in our markets and home scales for weight. Troy started from France in the Roman times and was adopted by Great Britain in the late 1500’s.
What Does Gold Karat Mean?
Definition of Gold Karat
The term “karat” (sometimes spelled “carat” outside the United States) is a measure of gold purity. It indicates the proportion of pure gold in an alloy, with 24 karats representing 100% pure gold. The word “karat” comes from the Greek word for the carob seed, which was used as a unit of weight for precious metals in ancient times.
Key Point: 1 karat = 1/24th part of pure gold in an alloy
How Karats Relate to Gold Purity
To understand the relationship between karats and purity, it’s helpful to think of gold in terms of 24 parts. The number of karats tells you how many of those 24 parts are pure gold. For example:
- 24 karat gold = 24/24 parts pure gold (99.99% pure)
- 18 karat gold = 18/24 parts pure gold (.750% pure)
- 14 karat gold = 14/24 parts pure gold (.583% pure)
- 10 karat gold = 10/24 parts pure gold (.417% pure)
Here’s a quick reference table to illustrate the relationship:
| Karat | Parts Pure Gold | Percentage Pure |
|---|---|---|
| 24K | 24/24 | 99.9% |
| 22K | 22/24 | 91.7% |
| 18K | 18/24 | 75% |
| 14K | 14/24 | 58.3% |
| 10K | 10/24 | 41.7% |
The 24-Karat Gold Standard
24-karat gold (commonly written as 24k) is considered the purest form of gold commercially available, containing 99.9% pure gold. It’s often referred to as “pure gold” or “fine gold.” However, it’s important to note that absolutely 100% pure gold doesn’t exist outside of laboratory conditions, as even 24-karat gold contains minute traces of other elements.
Fun Fact: The largest pure gold nugget ever found, the “Welcome Stranger,” weighed 2,316 troy ounces (72 kg) and was discovered in Australia in 1869.
While 24-karat gold is the purest, it’s not always the best choice for all applications. Pure gold is extremely soft and malleable, making it unsuitable for many types of jewelry that need to withstand daily wear. This is why gold is often alloyed with other metals to increase its durability and strength.
At CV Coins and Collectables, we deal with gold of various karats, from pure 24-karat gold coins to 14-karat gold jewelry. Our expertise allows us to accurately assess the value of your gold items based on their karat rating and weight. Understanding gold karat’s meaning is just the first step. In the following sections, we’ll dive deeper into gold purity charts, testing methods, and factors that affect gold value.
