Raindance or Sabbia

Tidy rows are what both refuse, by opposite routes. Pomellato's Sabbia, Italian for sand, packs white, brown and black diamonds of mixed sizes and cuts over a dome, hand-set at different heights so the surface shifts like a beach in low sun. Raindance, from Boodles in 2000, spreads its round diamonds thin: unequal stones, each in its own collet, scattered across open platinum bands. The Milan version is warm and dense in rose gold, the London one cool and open, and both took patient hands to look this unplanned.
