About this 1.2ct lab-grown cushion diamond

This 1.2ct 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 LG591326504 or 591326504. Listed at 4 retailers as of November 4, 2026, with prices from $819 to $1,661, a $842 spread on the same certified stone. Jared lists it at $1,661. 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.
