Karat is the unit that is used to measure the purity of gold. The higher the karat in a gold item, the purer the gold in it would be. Be it molded into coins, bars or precious jewellery; gold is available in a variety of karats, and these karats are used differently.
The 100 per cent pure gold is 24 karat gold, as it doesn’t include any traces of other metals. It is said to be 99.9 per cent pure in the market and has a distinct bright yellow color. As it is the purest form of gold, it is naturally more expensive than other types. 24k gold is normally used to make gold coins and bars. However, a tiny amount of alloy is also mixed in 24K gold coins to make them durable. It is also apt to be used in certain electronics and medical devices.
The 22 Karat gold is commonly used in making regular jewellery. 22K means that 22 parts of the metal amount to gold and the rest two parts are some other metals that make the texture of gold harder, thus making the metal durable. This form of gold is often found in a lot of wedding jewellery and other items that are worn occasionally.
18 karat gold comprises 75 per cent pure gold mixed with 25 per cent of other metals like copper or silver, etc. Highly suitable for making studded and diamond jewellery, 18k gold is less expensive as compared to 24K and 22K. This type of gold has a rich yellow tone with a slightly dull shade that makes it absolutely desirable for exquisite gold and diamond jewellery pieces. Jewellery made out of 18k gold is suitable to wear daily.

Precious Metals – Yellow Gold
Yellow gold is a precious metal with warmth and lustre. It can be kept clean and lustrous with a specialist cleaning cloth or fluid. Periodic specialist cleaning and polishing by any jeweller is also recommended.
Precious Metals – White Gold
White gold is a precious metal that is both beautiful and popular. The white lustre is enhanced by rhodium plating (rhodium is a member of the platinum family) which with general wear will fade over time. Therefore white gold requires a higher maintenance to retain its lustre. To restore the white lustre re-rhodium plating periodically is required. This specialist procedure can be carried out by any jeweller.

Sparkling jewellery with gemstones may have high resistance but they are not indestructible. To maintain the beauty and sparkle of your gems and gem-studded jewellery, you have to treat them with care.
- Most stones respond well to mild detergent and warm water.
- Scrub them using a soft brush, preferably a baby brush with soft bristles.
- Rinse the stone and dry it gently with the help of a soft, lint-free cloth.
- Always rinse your gem-studded jewellery in a bowl of water. Sometimes the stones on a piece of jewellery become loose in their settings. Rinsing them in a sink or wash basin poses a risk of losing such gems.
- Store Your Gemstone Ornaments Separately
- Diamonds are the hardest stones in the world closely followed by rubies and sapphires. Emeralds, topazes, and aquamarines come next in the hardness scale. Pearls and peridots are comparatively softer gems. On the hardness scale, they are only half as hard as a diamond or ruby. That is why you should store your gems separately. If you store all such ornaments together, your diamond rings may rub against your pearl bracelet, thereby causing damage to the latter. The best way out is to store them in separate compartments of your jewellery box. Keep in mind that some gems like opals and pearls draw moisture from the air. So, avoid storing them in safe deposit boxes. It is best to store such jewellery in a jewellery box with fabric lining.
