This composition gives a clear explanation about the rift between its market values.Gold vs Platinum | What's the Best Metal for Your Ring,Gold vs Platinum Cost. While gold and platinum are similar in price per gram, platinum is more dense and so more of it is required to make a ring. Additionally, platinum rings are usually 95% pure platinum, while 14k gold is only 58.5% gold (18k gold is 75% gold). Therefore, platinum rings are more expensive. Gold vs Platinum Durability
