We believe that our 23.5-karat gold electro-plating over yellow bronze is more durable than traditional vermeil plating, which requires a thickness of at least 1.5 microns of 10-karat gold over sterling silver. We use 2.5 microns of 23.5-karat gold plating over recycled yellow bronze. We use yellow bronze because it extends the lifetime of the gold plating and is the only base metal that allows for repair if it gets scratched.
Our gold-fill chain is constructed by layers of gold bonded to a surface with heat and pressure. We prefer to use gold-filled chain because it is more durable than electro-plated chain. Unfortunately, it isn't possible to use the gold-fill process for our sphere charms, which is why we use a very thick electro-plating as mentioned above.
Rhodium is a metal we electro-plate over some of the sterling silver chain of our Hepworth Silver Necklace to add shine, luster and durability.
Black Rhodium is a metal we electro-plate over certain parts of the Silver Gem Drop earrings to add contrast between the sterling silver and cultured white diamonds.
