Most important when buying gold is if it’s hollow or solid. To many, this is a huge durability factor. How to tell the difference is by weight.
Hollow gold is easy to spot with a lower price tag. Then once you pick it up and feel the weight, you will know. It’s so light that you may think it’s for display. Keep in mind it can be damaged quickly.
Solid gold is most sought after since it's known to last the longest. As far as quality and durability, this is the best choice. You can wear every day with no hassle.
