Trouvaille Semi-Mount for Round Center, 0.41 CTW, 14K Two-Tone Gold

At the antique shop on the square, she picked up a small brass candlestick, turned it once toward the window light, studied the seam where the base met the stem, and set it back down without a word. Four months later you found out she'd been thinking about it the whole time.

She's done this since the candlestick: she reads how a thing is put together before she ever says whether she wants it. This setting is built for exactly that kind of read. The head lifts into a soft peak, tiara-shaped, waiting to hold a stone of about a carat and a half. Along the shank, warm gold and white gold meet edge to edge, a detail she'll notice before she notices the diamonds. The center stone isn't set yet. You choose that part, and once you do, she'll be the only other person who knows what it means.

This is a semi-mount setting built to hold a center stone of about 1.5 carats, chosen and set separately. The Endless collection band and Signature Tiara head are crafted in 14-karat gold, two-tone, with a round head style and a traditional shank width. Thirty-eight round diamonds line the setting, G/H in color, VS1 in clarity, 0.41 carat total weight.

She takes her time with everything she actually wants, and she'll take her time with this too, saying nothing until she's certain. Choose the diamond that finishes it, and she'll know exactly how well you were paying attention.
