This 1.26ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG605354224 or 605354224. Listed at 9 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.
