About this 1.21ct lab-grown cushion diamond

This 1.21ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG579384441 or 579384441. Listed at 8 retailers as of November 5, 2026, with prices from $621 to $2,080, a $1,460 spread on the same certified stone. MOH London lists it at $2,080. 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.
