This 1.23ct lab-grown radiant sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG638428759 or 638428759. Listed at 16 retailers as of November 6, 2026, with prices from $332 to $2,562, a $2,230 spread on the same certified stone. Do Amore Diamonds lists it at $2,562. 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.
