Gold jewelry comes in many purities, and terms like 18K, 22K, and 24K can confuse buyers. Understanding gold karat helps you choose the right jewelry based on durability, shine, and value. This guide breaks it down in a simple and clear way so anyone can understand gold purity levels.
1. What Does “Karat” Mean in Gold?
Karat (K) is a measurement that shows how pure your gold is.
Pure gold is divided into 24 parts, so:

24K = 24/24 parts gold = 99.9% pure
-
22K = 22/24 parts gold
-
18K = 18/24 parts gold
Karat just tells you how much gold is mixed with other metals like copper, silver, or zinc. These metals add strength and color to the jewelry.
