take it to a jeweler
Platinum's inability to form compounds with oxygen indicates that it is a relatively unreactive element. This is because it requires a high amount of energy to break the strong bonds between platinum atoms to form compounds with oxygen.
Silver is generally lighter and softer than platinum. Silver also tarnishes over time, developing a black or gray patina, whereas platinum retains its white luster. Additionally, platinum is more resistant to corrosion and is more valuable than silver.
One of the easiest ways to tell the difference between stainless steel and platinum jewelry is by the markings. Platinum will have a marking such as "Plat", "PT", or will have "Platinum" etched in the piece.
Authentic platinum jewelry will be stamped with a hallmark indicating its platinum content, such as "Pt" or "950 Plat." You can also have the piece tested by a professional jeweler using methods like acid testing or X-ray fluorescence analysis to confirm its purity. Counterfeit platinum may feel heavier than expected, have discoloration, or lack a proper hallmark.
One way to distinguish between silver and platinum is by their markings. Silver is typically marked with "925" or "sterling", while platinum is marked with "PLAT" or "950". Additionally, platinum is heavier and denser than silver, so you can weigh the ring to help determine the metal. If you're still unsure, a jeweler can perform a professional assessment.
