Semi-Mount for Princess Center, 0.02 CTW Diamonds, 14K White Gold

At her sister's rehearsal, the wedding coordinator had the whole bridal party walking in matched pairs, evenly spaced, the same order as the last four weddings you'd both sat through. Your girlfriend raised her hand and asked why. By Saturday the pairs were gone, and her sister thanked her for it.

Hand her a finished ring off the shelf and she'll ask why that stone, why that cut, why now. This setting doesn't answer for you. The head sits empty, shaped for a princess-cut center stone, and six round diamonds trace the tiara around where it will sit. You still have to choose the stone yourself. That's the part she'd actually want you to get right.

This is a semi-mount setting in 14-karat white gold, polished, with a Signature Tiara head shaped for a princess-cut center stone, not included, built to hold a stone of about 1 carat. Six round diamonds, G-H in color, VS1 in clarity, are set through the shank for a total weight of 0.02 carats. The shank is from the Adored collection, in a solitaire style.

This is the one ring she can't talk you out of, because you're the one who chose the stone.
