White gold and platinum are two metals that looks the same. Therefore, many people always confused about what is the difference between them. Platinum is more expensive metal. Here are some mentioned differences between two metal – as well as their advantages and disadvantages.
What is white gold?
Actually white gold doesn’t exist naturally. It is the combination of yellow gold and white alloys like palladium or silver. After that, it is coated with a rare, silvery-white metal called rhodium. The rhodium gives white gold its final luminous sheen.
Why white gold mixed with other metals?
Gold is extremely soft metal so it is combined with other alloys to make white gold. If only pure gold is used for making jewelry, it would bend out of shape very quickly. For this reason, white gold and yellow gold is mixed with harder alloy metals, to make them more rigid and durable in jewelry.
All jewelry pieces are made with precious metal alloys, they contain a specific set of carat weights of gold. The gold carat weights were commonly seen in 9k, 14k and 18k jewelry;
- 9k gold contains 37.5% pure gold.
- 14k gold contains 58% pure gold.
- 18K gold contains 75% pure gold.
What is platinum?
Platinum is more expensive than gold and it is naturally occurring white metal. It is more rare, heavier and harder than gold. Platinum is used in its pure form because of its hardness.
Is platinum scratch proof?
Platinum is not scratch-proof material. Its surface can develop small bumps and ridges. This is especially true in case of engagement and wedding rings worn on your hand on special day and they come into constant contact with a hard surface. This surface ridging in platinum jewelry is called “the patina of age”. It is viewed as desirable. The patina shows an item of platinum jewelry is much loved and used and gives it an antique heirloom feel.
Platinum vs White Gold
White gold is much more affordable than platinum. However, the disadvantage is that you may need to recoat your white gold item in rhodium once or even twice a year.
This is because the wear and tear rub away the outer coating. Eventually, the yellow gold underneath becomes visible. Recoating white gold jewelry with rhodium is an easy and less expensive process.
But it does mean that you’ll need to maintain your jewelry regularly – over the years this cost can build up. In the case of engagement rings, you may also need to be without your ring for a few days, while it’s being recoated.
Platinum jewelry is more expensive than white gold. However, it can be argued that platinum is more cost-effective in the long run because it does not need to be recoated.
