This 1.23ct lab-grown radiant sits in the classic one-carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG670440093 or 670440093. Listed at 2 retailers as of November 2, 2026, with prices from $684 to $828, a $144 spread on the same certified stone. Diamond Quarter lists it at $828. 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.
