Endless by Trouvaille Halo Semi-Mount for Round Center, 14K White Gold

She stood in front of the painting for four seconds and said "that one," before you'd even found the little card with the artist's name.

You've watched her do this a dozen times now. No debate, no walking the room twice, just a straight line to the piece that's right and she's done deciding. So don't hand her a finished ring and hope she loves the setting around a stone you picked alone. Show her the setting first: a halo of diamonds that spills down around the center like a waterfall instead of sitting flat in one ring, cast in the cool white gold that actually looks right against her hand. Let her decide on sight, the way she always does. Then you go find the diamond that goes in the middle.

This is a setting built to hold a round center stone of about 1.5 carats, chosen separately and set in after purchase. The waterfall halo carries two rows of round diamonds: thirty-eight stones totaling approximately 0.41 carat and forty-four stones totaling approximately 0.40 carat, G/H in color and VS1 in clarity. The halo and band are cast in 14-karat white gold, from the Endless collection, on a traditional shank.

She won't need the center stone to know this one's right. One look at the setting, and she's already decided.
