This 1.28ct 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 LG836664301 or 836664301. Listed at 8 retailers as of November 6, 2026, with prices from €185 to €811, a €626 spread on the same certified stone. NZ Jewellers lists it at €811. 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.
