1. Check the Mark
Authentic 925 silver jewelry will usually be engraved with "S925," "925," or "Ag925" on the inside. This is the internationally recognized designation for sterling silver. If you can't find the mark or it's faint, be cautious.
2. Observe the Color
925 silver is a lustrous white, but slightly darker than platinum. If the color is too shiny (like stainless steel) or too yellow (like copper), it could be fake.
3. Magnet Test
Silver is a non-magnetic metal and will not be attracted to a magnet. If jewelry is attracted to it, it contains impurities such as iron and is definitely not pure silver.
4. Nitric Acid Test (Proceed with caution)
Place a drop of nitric acid in an inconspicuous area. Authentic silver will turn green but retain its luster; fake silver may turn black or corrode. However, this method can damage the jewelry, so it is recommended that you have it performed by a professional.
5. Listen to the sound
Gently drop the jewelry. Real silver will make a dull, non-bouncy sound, while fake silver (such as silver-plated alloy) will make a crisp, resonant sound.
