Gold-plating: Gold-plated finishes are considered to be the best finishes and gives higher value to the product.  Gold-plating results in a very stable, non-corrosive finish. WKC uses an electroplating bath that results in a 24-carat-gold finish that is about 99.3 to 99.7 percent of gold. Gold plating is also highly resistant to any discoloration over time.
