About this 0.51ct lab-grown cushion diamond

This 0.51ct 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 LG620494544 or 620494544. Listed at 6 retailers as of November 5, 2026, with prices from $265 to $1,339, a $1,074 spread on the same certified stone. MOH London lists it at $1,339. 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.
