Learn how karat markings describe gold content and why alloys are used in jewellery.
Gold purity describes how much gold is present relative to other metals. In the karat system, 24K represents a very high gold proportion, while 18K, 14K and 10K contain progressively more alloy.
Alloying can change colour, hardness and wear characteristics. A lower karat number is not automatically the wrong choice; intended use, design and care all matter.
Marks are useful clues, not a substitute for professional inspection. An evaluation can consider construction, weight and suitable testing methods.
