Understanding the Differences Between White Gold and Platinum

In terms of engagement rings, gold and platinum are the most famous choices because of their value, durability, and appearance. Both platinum and white gold feature a sleek, contemporary look and are perfect for modern engagement and wedding ring designs. But, these metals have significant differences when it comes to composition, purity, durability, price, and look. Read on to understand each difference:

Purity

Usually, platinum or gold is alloyed with other elements to make a more workable and durable metal. The majority of platinum alloys have between 85 percent and 95 percent platinum. The rest of the alloys are made up of metals such as cobalt, palladium, and copper. Moreover, white gold alloys have a lower percentage of pure gold. 18K gold has 75% pure gold.  The rest of the alloy is made up of nickel, copper, or silver.

Color

White gold and platinum are both silver-hued. However, platinum is naturally white while white gold is created. White gold is made by mixing yellow gold with other metals to come up with a yellowish-whitish metal. White gold tends to be more shiny and reflective than platinum because of its rhodium coating.

Hypoallergenic Properties

Because platinum is bio-compatible, it does not cause skin reactions for those who are sensitive to metals. Although pure gold is hypoallergenic, white gold may cause allergies because of the metals in its alloy such as nickel and zinc. To avoid sensitivities, it is best to choose white gold which is an alloy of gold, copper, and silver.

Density

Compared to gold, platinum is quite dense and heavier. Platinum is around 60 percent heavier than 14k gold and around 40 percent heavier than 18k gold. When it comes to comfort, a platinum ring tends to feel heavier than a white gold ring. Although some people prefer the solid feel of platinum, others are likely to choose a slightly less heavy white gold ring.

Price

Gold and platinum have about the same price but platinum is more expensive. But, when created into jewellery, pieces made of platinum are usually more expensive than white gold. The difference in price is caused by the following:

  • Platinum is rarer than gold and mined in only a few locations across the globe.
  • Platinum jewelry is heavier than gold jewelry of the same size.
  • Making platinum jewelry requires the use of specialised tools, a higher level of expertise, and higher temperature levels.
  • Platinum jewellery is usually 95 percent pure while gold jewellery is nearly always under 75 percent.
