About this 1.23ct lab-grown cushion diamond
This 1.23ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG656488285 or 656488285. 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.
