This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 815669821. Listed at 12 retailers as of November 4, 2026, with prices from €4,902 to €8,908, a €4,006 spread on the same certified stone. MOH London lists it at €8,908. 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.
