Should I choose 10K, 14K, or 18K gold for this piece?

Is this solid gold all the way through, or just gold-plated?
This piece is solid gold throughout, not gold-plated — the karat purity runs all the way through the metal. Unlike plated jewelry, it won't flake, discolor, or expose base metal over time, and it carries a karat hallmark stamp as proof of authenticity.
