About this 0.5ct lab-grown cushion diamond

This 0.5ct lab-grown cushion sits in the half to three-quarter carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG620494551 or 620494551. Listed at 6 retailers as of November 1, 2026, with prices from $261 to $1,322, a $1,061 spread on the same certified stone. MOH London lists it at $1,322. 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.
