This is created when a jewelry piece is casted in a single toned color – Either full 18K white gold, 18K rose gold or 18K yellow gold. Thereafter, when the crafting of the jewelry piece is completed, it is partially and artificially plated with a different color as compared to its base color to create a distinctive two-tone contrast color visually similar to a Solid-Two Toned 18K gold piece.

This method is used only when the design does not allow for it to be crafted as a solid two-toned gold . For example, an 18K White Gold ring may have certain parts of the ring plated in Rose Gold to give a two-toned effect.

The base color of a plated Two-Toned 18K gold jewelry is the same throughout the entire piece. Any secondary colors are plated on the surface. Therefore, through daily wear and as the jewelry gets into contact with the skin and other surfaces the external plating may wear off over time revealing its base color.
