Singapore chains in solid 14K yellow gold, from 1mm.
The link. Diamond-cut curb links twisted so the chain spirals. It has a liquid movement no straight chain has, and it catches light continuously rather than in one place.
Caution. Singapore kinks more easily than a rope. Store it hanging rather than coiled.
