The Core Difference
Platinum is a luxury metal priced at 20–40x the cost of sterling silver. It is denser, more durable, never tarnishes, and is fully hypoallergenic. Platinum is the premier choice for engagement rings and fine jewelry intended to last a lifetime. Sterling silver is the most accessible precious metal, ideal for fashion jewelry and everyday accessories where the goal is style, variety, and value.
