Jewellery education helps individuals understand the value, quality, and craftsmanship behind precious metals and gemstones. In gold, purity is measured in karats (K), with 24K being pure gold, while 22K, 18K, and 14K indicate the percentage of gold mixed with other metals for strength and durability. Diamonds are graded based on the 4Cs – Carat (weight), Cut, Color, and Clarity – with the carat indicating the stone’s size and weight. Learning these fundamentals enables buyers to make informed choices, appreciate fine jewellery, and understand its true worth.
