Gold Purity Guide
What Does Karat Mean?
Karat (K) measures how much pure gold is in an alloy. Pure gold is 24 karats — meaning 24 out of 24 parts are gold. 22K means 22 parts gold and 2 parts other metals (copper, silver, zinc). The higher the karat, the purer the gold — but also softer and more expensive.
24K Gold 999 fineness
99.9% pureThe purest form of gold available commercially. Too soft to hold shape in jewelry — bends and scratches easily. Bright yellow color with no reddish or whitish tint.
22K Gold 916 fineness
91.6% pureThe standard for Indian gold jewelry. Mixed with 8.4% copper/silver for durability while maintaining a rich gold color. Strong enough for daily wear yet retains high gold value. This is what most Indian jewelers sell.
18K Gold 750 fineness
75.0% pureHarder than 22K due to higher alloy content. The extra hardness makes it ideal for setting diamonds and gemstones — the prongs hold stones securely without bending. Available in yellow, white, and rose gold tones depending on the alloy mix.
14K Gold 585 fineness
58.5% pureThe most durable gold alloy for jewelry. Very resistant to scratches and tarnishing. Popular for everyday rings, bracelets, and chains that take a lot of wear. More affordable per gram than higher karats but lower gold content means lower resale.
