I've never seen an engagement ring where the metal work and accent stones together cost more than $1,000 to make in 18K gold. And that's with our profit margin included.
Engagement ring and band together should be under $1,500 in metal.
Women's settings don't cost much unless you do something stupid like surround the entire band in tiny diamonds so she has a million prongs poking her fingers and you are forever paying as stones fall out. [8/8?]
