Beloved by Trouvaille Semi-Mount for Princess Center Two-Tone 14K Gold

She stood in front of a wall of paintings at the gallery opening, looked at the whole room for maybe four seconds, and pointed at the smallest canvas in the corner. Everyone else was still reading the placards.

You'd have stood there another twenty minutes weighing all hundred canvases. She was done in four seconds, because she wasn't choosing between all of them. She already knew what she was looking for. That's the head waiting empty at the center of this setting: cut for a princess stone, four sharp corners, nothing rounded off to make the choice easier. You're the one who picks what goes inside it.

This is a solitaire engagement setting in two-tone 14-karat gold, worked in the Signature Tiara style along the shank. The head is cut for a princess-shaped center stone and built to hold a stone of about 1.50 carats; the center stone is sold separately. Sixteen round diamonds run the band, G-H in color, VS1 in clarity, for a total weight of 0.38 ct.

You pick the diamond. She'll know in an instant that you got it exactly right.
