There is not a single best type of gold for everyone. You must keep factors like skin sensitivity, activity level, and aesthetic taste in mind. You also need to keep your budget in mind. For most customers, 14-karat gold offers the most significant advantages. It provides the best combination of beautiful color, good durability, and reasonable affordability. It is also the most common type of gold in the United States, so it offers more options. But 18-karat gold would be best if you prefer something more luxurious. It is also perfect if you do not mind trading some durability for a richer gold color. You just need to be more careful when wearing jewelry pf this type of gold as it could easily scratch.
