What does 750, 916, 999 gold really mean?
If you've ever shopped for gold jewellery, you've probably noticed numbers like 750, 916, or 999 stamped on the piece. While they may look like serial numbers, they're actually one of the easiest ways to understand the purity of your gold.

What do the numbers represent?
The numbers indicate how much pure gold is contained in the jewellery.
999 Gold = 99.9% pure gold (also known as 24K gold)
916 Gold = 91.6% pure gold (also known as 22K gold)
750 Gold = 75% pure gold (also known as 18K gold)
The remaining percentage is made up of other metals, such as silver or copper, which improve the jewellery's strength, durability, or colour.
999 Gold – The Purest Form
With 99.9% pure gold, 999 gold is prized for its rich yellow colour and high purity.
Because it is very soft, it is commonly used for gold bars and investment pieces, traditional gifts, and collectibles.
It is generally less suitable for jewellery that is worn every day, as it can bend or scratch more easily.
916 Gold – Singapore's Favourite for Jewellery
916 gold contains 91.6% pure gold, making it an excellent balance between purity and durability.
This is why it remains one of the most popular choices for jewellery in Singapore.
Many customers choose 916 gold because it offers the luxurious appearance of high-purity gold while being durable enough for regular wear.
750 Gold – Designed for Everyday Wear
750 gold, also known as 18K gold, contains 75% pure gold.
The higher proportion of alloy metals makes it stronger and more resistant to scratches than higher-purity gold. It is commonly used for diamond or gemstone jewellery.
How Can You Be Sure It's Genuine?
Always look for a recognised hallmark that verifies the gold's purity.
At Arthesdam Jewellery, our gold jewellery is hallmarked by the Singapore Assay Office (SAO), giving customers added confidence that the gold has been tested and certified for its purity.
Buying from an established jeweller and checking for proper hallmarks are two of the simplest ways to ensure you're purchasing genuine gold jewellery.
Final Thoughts
Whether you choose 750, 916, or 999 gold, understanding what these numbers mean helps you make a more informed purchase.
If you're looking for jewellery that combines beauty, durability, and lasting value, 916 gold continues to be one of the most popular choices among Singaporean shoppers, while 750 gold is ideal for gemstone jewellery and 999 gold remains the preferred option for those seeking the highest gold purity to hold value best.
