Different types of gold karats

Karat is the term used to measure the purity of gold. Before we understand the difference between 24k, 22k and 18k gold, you must know what karat stands for. Karat is basically a unit used to measure the purity of gold. The higher the karatage, the purer the gold. Here’s a simple guide to understanding the difference between 24k, 22k and 18k gold.
• 24K gold
24k gold is also called pure gold or 100 per cent gold. This means that all 24 parts in the gold are all pure gold without traces of any other metals. It is known to be 99.9 per cent pure and takes on a distinct bright yellow color. There is no higher form of gold than 24K and you must be aware of this before you go to a dealer who might tell you that they’re selling you 25K or 26K gold. Since this is the purest form of gold, it is naturally more expensive than 22K or 18K gold. However, this type of gold is lesser in density as compared to gold of a lower karatage which makes it soft and pliable. Hence, it is not suited for regular forms of jewellery. Coins and bars are mostly bought of 24K gold purity. 24K gold is also used in electronics and medical devices such as those used for children suffering from ear infections who are fitted with gold tympanostomy tubes that are known to improve aeration of the middle ear.
• 22K gold
22K gold jewellery implies that 22 parts of the jewellery amounts to gold and the balance 2 parts are some other metals. This kind of gold is commonly used in jewellery making. In 22K gold, of the 100 per cent, only 91.67 per cent is pure gold. The other 8.33 per cent comprises metals like silver, zinc, nickel and other alloys. It is this addition of metals that make the texture of gold harder thereby making the jewellery durable. However, you must know that although this can be used to make plain gold jewellery, 22K gold isn’t preferable for diamonds and heavily studded jewellery.
• 18K gold
18K gold is 75 per cent gold mixed with 25 per cent of other metals like copper or silver etc. Usually studded jewellery and other diamond jewellery is made in 18K gold. This kind of gold is less expensive compared to 24K and 22K. This one has a slightly dull gold colour. Recognizing 18K jewellery is rather simple – you will see the item stamped with 18K, 18Kt, 18k or a variation similar to these. At times, 18K gold is marked by 750, 0.75 or a stamp similar to these in order to symbolise that the jewellery contains 75 per cent gold.

Varalaksmi Nimmagadda

I, Varalakshmi Nimmagadda am incessant learner and a voracious reader.I love literature and my  love of literature has not stopped with my post graduation in English but manifested as invaluable books useful for generations. I have not only the zeal but also the guts to choose the great Sanskrit work for translation. Guided by fervour i brought out Umasahastram [1000 sanskrit slokas] into Telugu with many months of strenuous devout and diligent work only a woman of substance can do that. To make books in PageMaker, I have learnt DTP – compiling and making books.

I work with page maker laboriously into late nights, since my husband also writes in Telugu, English and foreign languages, my work gets doubled and I get extreme physical exhaustion, and from that physical exhaustion I derive satisfaction. I have abridged [shortened] many voluminous but vital books of inspiration like Swamy Jnananda a professor-sage who headed the Nuclear physics department of Andhra University.

I  love music and to quench my thirst I did diplomas in music (veena and vocal). I did M.B.A. and worked as M.B.A. faculty. But my love of reading admiration pulled out from teaching. After reading hundreds of books of a variety of genres of English literature I began translating English books into Telugu and vice versa.
