This 1.28ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG801643283 or 801643283. Listed at 4 retailers as of October 28, 2026, with prices from €994 to €1,384, a €390 spread on the same certified stone. Zales lists it at €1,384. 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.
