About this 1.21ct lab-grown cushion diamond

This 1.21ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG632450946 or 632450946. Listed at 3 retailers as of November 4, 2026, with prices from $827 to $1,674, a $847 spread on the same certified stone. Jared lists it at $1,674. 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.
