This 1.25ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG844685090 or 844685090. Listed at 4 retailers as of November 5, 2026. 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.
