The rivière, a river at the neck
A rivière is a river at the neck. Not a sautoir that travels down the body. Not a festoon that swags. A matched close line of stones, each in its own collet, linked so the necklace can lie on the bone. One temperature. No drop required. The length is the collar. The jewel is the line.

An American line, about 1900–20: visit the river first. Small diamonds, each held in a thin circular cup, a flexible sparkle that would sit as a cool ridge at the throat. That is the rivière — collet next to collet, one white weather all the way around. A pearl in the clasp. Then, below, a bow and a kite of yellowing stones. Those are the extra sentence. The drop is not the necklace. You would feel the matched line before you found the point. A rivière is already complete when the last collet meets the first.
One temperature, no fall
A sautoir has somewhere to go. A rivière stays. Collar, rivière, sautoir: three distances. This one chose the bone and kept a single temperature — no fringe, no swag, no need for a pear to finish the thought. You could wear the line alone and the neck would still read as a river. The bow, if it is there, is only a knot in the current. The kite is weather at the end. The icon is the collets: a close, even light that does not ask to hang.
That is the sit. A river of cups. Worn as a temperature, not as a story that has to end in a point.
