This 1.4ct natural cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 720508502. Listed at 7 retailers as of November 1, 2026, with prices from $4,433 to $8,671, a $4,238 spread on the same certified stone. MOH London lists it at $8,671. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
