One way to determine if jewelry is platinum is by looking for a stamp or hallmark on the piece that says "PLAT" or "PT." You can also check for the metal's silver-gray color, weight, and density, as platinum is heavier and denser than other metals like silver and white gold. Finally, consider getting a professional appraisal or using a testing kit to confirm the metal's composition.
