Gold Purity Explained – All You Need to Know

When talking about Gold Purity, the measure of gold content expressed in karats or millesimal fineness that tells you how much pure gold is in a piece. Also known as gold fineness, it determines value, durability, and which designs are best for everyday wear. Understanding purity helps you avoid cheap knock‑offs, price your own pieces accurately, and choose the right metal for a special occasion.

Key Marks and What They Mean

In India the most common purity level is 21K Gold, denoted by the 875 stamp, meaning the alloy contains 87.5% pure gold. This blend offers a nice balance of richness and hardness, making it ideal for heavy necklaces and traditional jewellery. The BIS Hallmark, a seal from the Bureau of Indian Standards that guarantees the stated purity is the safety net you look for when buying from a shop or online. If you see a 916 mark, that’s 22K (91.6% pure) and shines brighter but bends more easily. Lower numbers like 750 (18K) or 585 (14K) are often used for designs that need extra strength or for mixed‑metal pieces.

Beyond the stamps, the actual gold price you pay ties directly to purity. Higher purity means a larger share of pure gold, so the market price per gram goes up. Many buyers time their purchase around market dips, but the purity remains the constant factor that dictates resale value. Using a simple test—like checking the stamp, measuring weight against volume, or a magnet test for hidden alloys—lets you verify that the claim matches reality.

Knowing these basics also helps when you’re selling or inheriting jewellery. Certified BIS‑hallmarked pieces fetch better offers because buyers trust the authenticity. If you own unmarked antiques, a reputable jeweller can run a touch‑stone test and issue a new hallmark, effectively converting an uncertain item into a verified investment.
