Gold Purity Chart: Understanding the Different Levels of Gold Purity
Gold purity chart: Gold purity refers to the percentage of pure gold contained in an item, measured in karats (K) or parts per thousand.
The higher the karat, the purer the gold — with 24K (999) being the purest form, and lower karats containing a mix of gold and other metals for added strength.
Understanding gold purity is crucial for making informed buying, selling, or investment decisions, as purity affects value, durability, and resale potential.
This gold purity chart will help you easily compare different karat levels, from 24K investment-grade gold to 14K everyday jewelry, ensuring you choose wisely.
What is Gold Purity?
Gold purity measures the amount of pure gold mixed with other metals to form an alloy. Pure gold, known as 24-karat (24K) gold, is soft and malleable, making it unsuitable for crafting durable items like jewelry. To enhance its strength and durability, gold is often mixed with metals such as copper, silver, zinc, or nickel.
Gold purity is expressed in karats (K) or as a percentage. For example, 18K gold contains 75% pure gold, while the remaining 25% consists of other metals. This balance between purity and durability is essential for different applications, from investment-grade gold to everyday jewelry.
Gold Purity Levels and Their Applications
24K Gold (99.9% Pure): The purest form of gold, 24K gold boasts a bright yellow hue and a soft texture, making it ideal for investment in gold bars and coins.
It is also used in cultural items like gold foil and ornaments. However, its softness makes it unsuitable for jewelry as it is prone to scratches and dents.
22K Gold (91.6% Pure); 22K gold contains 91.6% pure gold and a small percentage of alloyed metals, which add strength and durability.
It is commonly used in high-quality jewelry, especially in regions like India and the Middle East, where its rich color and traditional appeal are highly valued. However, it is less durable than lower karat gold, making it more prone to wear and tear over time.
18K Gold (75% Pure); 18K gold strikes a balance between purity and durability, containing 75% pure gold and 25% alloy metals. Its rich color and relative strength make it a popular choice for fine jewelry, including rings, bracelets, and earrings.
Although slightly more expensive than 14K gold, its enhanced durability and luxurious appearance justify the cost for those seeking high-quality pieces.
14K Gold (58.3% Pure); 14K gold is favored for its practicality, blending affordability with durability. With 58.3% pure gold, it is commonly used in everyday jewelry such as necklaces, rings, and bracelets.
Its robust nature makes it resistant to scratches and dents, making it ideal for those seeking long-lasting wear. However, it is less pure than higher karat gold, which may affect its color and value.
10K Gold (41.7% Pure); 10K gold contains 41.7% pure gold, with a significant proportion of alloy metals. This composition makes it one of the most durable and budget-friendly options for jewelry.
Its resistance to scratches and dents makes it suitable for daily wear. However, its lower gold content gives it a duller color compared to higher karat options, which may not appeal to those seeking a more vibrant hue.
9K Gold (37.5% Pure); 9K gold represents the minimum standard for gold in some countries, with 37.5% pure gold. It is primarily used in affordable jewelry, offering a cost-effective alternative for buyers.
Despite its low gold content, it is durable and suitable for casual wear. However, its significantly reduced gold percentage means it lacks the richness and value of higher karat gold.
Which purity of gold is best:
When buying gold, purity matters because it directly affects value, investment potential, and resale price. Gold purity is measured in karats (K) or parts per thousand. 24K gold (999.9 fine) is the purest form, containing no alloy metals.
It’s ideal for investors and bullion buyers who want maximum value and easy resale worldwide. 22K gold (916 fine) contains a small percentage of alloy for added strength, making it popular for jewelry while retaining high value.
For long-term investment, 24K gold bars or coins are best, as they carry the highest market price and are recognized globally.
At Buy Gold Bars Africa Ltd, we recommend 24K gold for serious investors in Hong Kong and 22K gold for those seeking a balance between durability and purity.
Every purchase comes with an assay report and certificate of origin, ensuring authenticity and compliance with international standards.
Is 916 gold 22k or 24k
The number 916 means the gold is 91.6% pure, with the remaining 8.4% made up of other metals like silver or copper to give it strength.
Here’s the breakdown:
24K gold = 99.9% pure (often marked as 999 or 999.9)
22K gold = 91.6% pure (916)
18K gold = 75% pure (750)
So, if someone offers you “916 gold,” they are talking about 22-karat gold.
Which is better, 999 or 916 gold
999 gold is generally better than 916 gold if your goal is investment and maximum value, but 916 gold is better if you want durability for jewelry.
Here’s why:
999 Gold (24K)
Purity: 99.9%
Best for: Investors, bullion buyers, and collectors.
Pros: Highest value, easy resale worldwide, recognized as pure gold.
Cons: Softer and more prone to scratches or bending.
916 Gold (22K)
Purity: 91.6%
Best for: Jewelry and daily wear items.
Pros: Stronger, less prone to damage, still retains high value.
Cons: Slightly lower resale value than 999 gold due to alloy content.
For investment, choose 999. For wearable jewelry with lasting durability, choose 916.
