The difference between gold and platinum
Gold and Platinum are the most popular precious metals used in jewellery today for their inherent qualities of high economic value, lustre, resilience, durability and clarity. They can form alloys (mixtures) with other metals, creating a variety of attractive combinations for jewellery.
Undoubtedly, the most popular precious metal, gold is used in its “pure” form, meaning 24 karat (24K) gold or 18, 14 or 9 karat gold. 24K gold is soft, which requires it to be mixed with other metal alloys to increase its hardness and durability. Any piece that contains less than 24 karat gold should state the karat quality to guarantee the claim that the piece is made of gold.
Gold is available in several different colours: yellow, rose and white with yellow being the most popular. In some rare instances bronze, red and lime gold are also available. Jewellery can also be made through a combination of different gold nuances and such pieces are referred to as two-tone, three-tone or multi-coloured gold. The gold content of any type of gold is measured in the same way. For example, an 18ct white gold ring will contain 75% pure gold, similar to an 18ct yellow gold contains 75% pure gold. The metals used in the alloy mix determine the difference in colour between yellow, white and rose gold.
Platinum is a type of precious metal with value that exceeds that of gold. It is usually mixed with other similar metals, known as the platinum group metals, such as: iridium, palladium, ruthenium, rhodium and osmium.
Platinum jewellery bears different markings as compared with gold jewellery, based on the amount of pure platinum in the piece. These quality markings for platinum on parts are marked per thousand. For example, the marking 800 Platinum means that 800 parts out of 1000 are pure platinum, or in other words, the item is 80% platinum and 20% other metals. The abbreviations for platinum — Plat. or Pt. — is commonly used in markings.
Platinum is a prestigious choice and often chosen for its sophisticated appeal and popularity. Platinum is mainly used in engagement rings and wedding bands for both men and women for its universal appeal.
