I was thinking about incorporating aquamarine into an engagement ring. I have a March birthday, she has an April birthday. I've spent a little time looking, but the only thing I can find are halo rings with a center aquamarine stone. I was thinking about maybe a center diamond with a small aquamarine on either side. Anyone seen anything like that or think it would look good? What about a halo with aquamarines surrounding a diamond? I don't want anything too big or flashy looking, and would prefer to stay under 5-7k. Thanks!
