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

Is this solid gold all the way through, or just gold-plated?

What chain length should I choose?
16" sits at the collarbone, 18" is the most versatile everyday length, and 20"+ sits lower for a more dramatic look. Check the size options on this page for what's available.
