There’s no exact answer to this as it depends on your personal preference and style. In reality, both platinum and gold earrings both have their own unique properties and benefits. However, it’s worthy to note the differences between both of them:
1. Comfort and reactions: Platinum is a hypoallergenic metal, and as such, doesn’t trigger any skin allergy in its wearer. However, when considering gold, yellow gold is the most hypoallergenic version of gold (where white gold and rose gold have higher percentages of other metals mixed in them). As such, some people may be allergic to the base metals used in alloying gold, which can cause a reaction. In regards to comfort, the weight of gold is lighter and less dense than platinum, making it more comfortable to wear.
2. Maintenance: Yellow gold and rose gold require polishing, and sometimes replating to maintain their appearance, while white gold requires the most maintenance to maintain its colour; as it needs to be polished and replated every few years to prevent it from turning yellow. However, like every piece of jewellery, platinum also tends to scratch and can become dull over time. Although, it requires low maintenance home cleaning could help keep it bright and, when you polish platinum, it smoothens the piece without thinning the metal as such, can be done as often as you like.
3. Strength and Durability: Both precious metals are strong, although platinum is more durable, compared to gold. Platinum has a high density and chemical composition which makes it less likely to break, so it lasts longer, unlike gold. Platinum also offers no wear and tear on the metal when used in earrings. As such, platinum will not become thinner or lose weight like gold. Platinum, when scratched, only has a metal shift around a scratch without any loss whereas gold, when scratched, tiny particles of the metal are shaved off. Whichever metal you choose for your earring is based on your personal preference, budget, and style.
