Gold Purity Chart – Quick Guide to Karat Marks

If you’ve ever wondered what those tiny numbers and letters on a gold piece actually say, you’re not alone. Most shoppers see a 22K or 916 stamp and assume they know what it means, but the details can get fuzzy. This guide breaks down the common purity marks, shows you how to read them, and helps you decide which karat fits your style and budget.

Reading Hallmarks and Purity Marks

India uses a simple karat system: 24 karat (24K) is pure gold, 22K is 91.6% gold, 18K is 75%, 14K is about 58%, and 10K drops to 41.7%. These numbers often appear as a fraction (e.g., 22/24) or as a four‑digit hallmark like 916 (which means 91.6% purity). You’ll also see symbols for the maker’s logo, the year, and sometimes a BIS (Bureau of Indian Standards) mark for extra assurance.

• 24K – 999 or 999.9 purity (pure gold, very soft)
• 22K – 916 hallmark (most common for Indian wedding jewelry)
• 18K – 750 hallmark (good balance of durability and gold content)
• 14K – 585 hallmark (lighter, more affordable)
• 10K – 417 hallmark (budget‑friendly, least gold)

When you pick up a piece, first locate the hallmark. It’s usually stamped on the clasp, the back of a pendant, or inside a ring band. A clear, legible mark is a good sign, but remember that clever fakes can copy these numbers too.

How to Pick the Right Karat for You

Choosing a karat depends on three things: how you’ll wear it, how much you want to spend, and how much gold you actually want in the mix. If you need a piece for daily wear, 18K or 14K is a smart pick—still gold‑rich but tougher than 22K or 24K. For special occasions or traditional Indian weddings, 22K is the go‑to because it looks rich and matches the cultural vibe.

Budget matters, too. 24K looks amazing but dents easily, so you’ll pay a premium for the look and the extra care. If you’re on a tighter budget, 10K and 14K give you the gold feel at a lower price, though the color will be a bit paler.

Finally, think about resale value. Higher karats generally hold value better, especially 22K and 24K, because they contain more actual gold. If you plan to sell or upgrade later, aim for a higher purity mark.

When buying online, ask the seller for clear photos of the hallmark and a BIS certification if possible. Compare the gold price per gram with the listed karat to spot any mismatches. A quick magnet test (real gold isn’t magnetic) and checking the weight against a known size can also catch fakes before you click ‘Buy.’

With this gold purity chart in hand, you can read any stamp, understand what you’re paying for, and pick the right karat without second‑guessing. Happy shopping!
