Ag925 sterling silver earrings are coated with the following materials, depending on the tone:
Silver-tone Ag925 earrings: White Rhodium (RH, coating thickness 0.2μm) or Platinum (PT, coating thickness 0.4μm) – silver jewelry with white rhodium or platinum coating retains its original quality for a very long time. It does not tarnish or fade and is resistant to any discoloration. Visually, it is slightly darker than pure silver and resembles white gold.
Gold and rose gold-tone Ag925 earrings: Ag925 silver jewelry is coated with a double layer of 18K gold (AU) or rose gold. The gold base layer plus a top finish ensures a stronger and more durable gold coating. The thickness of the gold layer is 0.4μm.
