Choosing between gold and platinum when it comes to purchasing an item might be challenging due to their many similarities. They are valuable, elegant, durable, and adaptable. Both precious metals go with a wide range of designs, gemstones, and skin tones. Two popular jewellery materials are 18K gold and platinum. A lot of the jewellery we see on the market is made of 18K gold or platinum. Although they appear to be the same metal, they are two distinct metals with noticeable changes in material composition, price, inlay material, and durability.

18k Gold Vs Platinum

The main difference between 18k gold and platinum is that 18k gold is 75 percent of gold. It is a more durable metal. On the other hand, Platinum used in jewellery is more pure—typically, platinum contains 95-98 percent platinum, with the remainder made up of rhodium and silver. Platinum is the heaviest and densest precious metal, stronger and more durable than gold.

It's made up of 75 percent gold and 25 percent metal alloy. 18k gold has a somewhat brighter appearance than 14k gold. When you think of gold, the 18k colour is most likely what comes to mind. It's a deep yellow tint that looks fantastic with diamonds. The alloy is what gives the gold its strength and makes it suitable for everyday use. 18k gold is commonly used for engagement rings, anniversary rings, and other important occasions.

Platinum is the most ductile of pure metals, being more ductile than gold, silver, and copper, yet it is less malleable than gold. The metal is corrosion resistant, stable at high temperatures, and has consistent electrical characteristics. Platinum is mostly mined in South Africa, but it is also mined in Russia and Zimbabwe. Platinum is also a byproduct of the production of other metals such as nickel and copper. The majority of platinum comes from the mineral cooperite, commonly known as platinum sulphide.

What is 18k Gold

An alloy made up of 75% gold and 25% other precious metals is known as 18K gold. Gold and other metals are melted together to create 18-karat gold. Because it contains 75% gold, gold is the primary constituent. Because it contains 25% other metals, 18K gold can take on a variety of colours over time. White, rose, yellow, purple, and blue are just a few of the colours available in 18K gold. The varying colours of 18-karat gold are made up of differing quantities of other precious metals.
