Gold has symbolized wealth and power for centuries, and its appeal continues in 2025. Understanding the types of gold based on karat, purity, and colour is essential whether you’re buying jewellery, investing in coins, or pledging gold for a loan. This guide will help you navigate these key characteristics to make informed choices.
What is Gold
Gold is a chemical element that is widely used in jewellery, electronics, and as an investment option. It is prized for its rarity, durability, and aesthetic appeal. The value of gold is determined by its purity and weight, and it is measured in karats or fineness.
Gold Karat and Purity
The purity of gold is one of the most critical factors to consider when purchasing or investing in gold. The two main units used to measure the purity of gold are karats and fineness.
Karat System
Gold is measured in karats, with 24 karats being considered pure gold. Each karat represents 1/24th of the total weight of the metal. Here’s a breakdown of the karat system:
- 24 Karat (24K): Pure gold, 99.9% gold content. It is the highest purity gold available and is soft, making it less suitable for items subject to wear and tear, like rings or bracelets.
- 22 Karat (22K): Contains 91.67% gold. 22K gold is the most popular choice for gold jewellery, offering a good balance between purity and durability.
- 18 Karat (18K): Contains 75% gold. 18K gold is stronger and more durable, making it suitable for fine jewellery that needs to withstand daily use.
- 14 Karat (14K): Contains 58.33% gold. This lower purity gold is often used in items that require additional strength, such as watches and rings.
Fineness System
Fineness measures the purity of gold in parts per thousand, typically shown as a decimal or percentage. Pure gold has a fineness of 1000, though such purity is uncommon. For example, gold with a fineness of 0.950 has 950 parts of gold per 1000, equating to 95% purity.
Types of Gold Based on Colour
Gold is naturally yellow but can be alloyed with other metals to create different colours, enhancing its durability and strength. Each colour represents a different types of gold. Here are the common gold colours:
Yellow Gold
Yellow gold, the most traditional type, is made by creating an alloy of pure gold with copper and silver to preserve its golden hue. Its classic look makes it a popular choice for jewellery, especially wedding bands and necklaces.

Gold is not only used in jewellery but also in investment products like gold coins and bars. Here’s a comparison of gold jewellery and investment gold:
Gold Jewellery
Gold jewellery is a great choice for personal use or gifts, with its value based on purity, weight, and craftsmanship. When buying, consider the design and metal content, as the price includes making charges.
- Pros: Easy to buy and sell, versatile use, and can be worn as personal adornment.
