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 LG596324800 or 596324800. Listed at 4 retailers as of November 4, 2026, with prices from $827 to $1,163, a $336 spread on the same certified stone. Zales lists it at $1,163. 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.
