Fiorever or Sunflower

A single round brilliant sits at the heart of each, and there the likeness ends. Harry Winston's Sunflower of 1950 surrounds it with eight matched stones, plotted with a compass, so that the petals are gems too, mostly diamonds in platinum. Bulgari's Fiorever, from late 2018, gives the stone four petals of rose or white gold instead, a softer frame in sculpted metal, which later versions pave entirely.
