This 1.3ct lab-grown radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG534234422 or 534234422. Listed at 14 retailers as of October 30, 2026, with prices from €236 to €1,171, a €935 spread on the same certified stone. Reve Diamonds lists it at €1,171. 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.
