Rhodium Plating Adds Shine, Not Value
A lot of white gold jewelry is finished with a thin rhodium plating for extra shine and a whiter tone — but rhodium plating is a surface coating so thin it contributes essentially nothing to scrap value, and it wears off with years of daily wear regardless. When a buyer melts down a white gold piece, they're paying for the karat gold underneath the plating (and the nickel or palladium alloy mixed into it) — at the same 10K/14K/18K melt value as an identical-karat yellow gold piece, not a premium or discount for being "white."

Frequently Asked Questions
No — at the same karat, white gold and yellow gold have identical melt value. The alloy metals that make gold appear white (nickel or palladium, sometimes with a rhodium plating) don't add or subtract gold content, they just change color.
No. Rhodium plating is a thin cosmetic coating, not a meaningful amount of precious metal — a buyer melting the piece down is paying for the karat gold underneath, not the plating.
That premium (when it exists) is usually a manufacturing/finishing cost — rhodium plating, alloy processing — not a difference in scrap or melt value. On the selling side, both are valued the same way: weight × karat × the live gold price.
