This 1.01ct lab-grown radiant sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG605341573 or 605341573. Listed at 9 retailers as of October 31, 2026, with prices from €192 to €1,217, a €1,025 spread on the same certified stone. Do Amore Diamonds lists it at €1,217. 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.
